I have a problem with my computer (probably a motherboard) and from time to time it decide to change a date in BIOS. I noticed to late and when cam back to play with trial unity3d, it simle said that “trial has expired”. I try to reainstall trial again, but stil can’t use unity - stil have a situation “trial has expired”. I must say, that I use unity for about 5 days befor this happened. Any sugestion how to make trial work again?
Thx,
Denis
Same thing happened to me today. :x
At first I wasn’t sure it was a problem when the trial went from 28 days to 21 in 2 days… then today it just went into expiration status.
Anyways, at least I was somewhat able to test the editor, but what I wanted to do was to learn UnityScript (over the next few days of the trial…). Is there any other way to learn the script or will I just have to buy the Indie version (not cheap for me) just to see if I get the engine or not? (I am not a programmer… at all)
I was hoping that there was another way to learn UntityScript (actually testing the programs made using it) like LiteC from Atari (they have a Lite version without any limits). Is there? (else I’ll just move on) 
You can contact sales@unity3d.com and they’ll extend the trial.

OK, emailed the sales team. Though I don’t know if they will reset it now (at least I’ll be able to get the time problem fixed on my PC till then). 
I send a mail to sales@unity3d.com too. I wonder how long it takes… 
Some thoughts:
If your machine keeps doing this then additional trials may do the same, in that case you need to fix that problem as this is our licensing system behaving as intended. Clock resetting is commonly used to circumvent time based trials and we can’t keep issuing a long train of trials for you to get through it. This won’t be a problem with a permanent license as those aren’t time-based at all.
We generally answer emails within 24 hours, as of late we’re running slower than that due to the crushingly high volume since Unity 2.5, although we’re nearly caught up. To show love for my forum peeps, PM me your email addresses and I’ll make sure you get prompt replies.
Oh thank god… err, thank you Mr.Higgy. I just pmmed you the email address (going to celebrate now :mrgreen: ).
I need new computer, that for sure… Anyway, thanks for reactivate my trial version. I will never forget this
I have one more question about trial version. Would’n be more simple if trial version is valid for ever, but will has no option to build the project (make .exe)?
Thank again.

The point of a trial is to let you evaluate the product and make a purchase decision. We feel that a 30-day experience is enough to let you make that decision and hopefully a purchase. In a “it’s forever” trial you could have one person purchase a license and 10 people use the trial, everyone just has the one license holder produce builds. Not good.
30 days is enough, we extend that on request (Pro, iPhone, etc.). That’s a generous offer that lets people make the right call.
We feel that a 30-day experience is enough
I agree that a “it’s forever” trial would be to much. I would suggest that a 60-day experience would be more appropriate. I find I am using more time than I thought just getting things to run correctly, finding answers to questions, researching info in the forums, going through some of the tutorials (which are not quite up to 2.5’s ways yet), finding tutorials to help learn, and similar things. The 30 days will be up before I will be able to truly see if Unity is worth my sparse funds at this time. Just as I am about to get a feel for it my time will be gone.
It seems Unity is a good system, but that’s what I thought about GGs stuff. I am disappointed in it, but at this point I will just upgrade to T3D for the $505 unless I can see Unity being better for what I need. 30 more days would allow me to see if it will do more of what I want, not just how to get it to do something.
Again I counter: 30-days is plenty. With that in mind we extend trials on request as at times other things get in the way. You need to make sure you have a clear plate though as we only do that once. Write us at trial@unity3d.com or sales@unity3d.com to request an extension and we’ll set you up with one.
I’ll see your counter and raise you one. 
30 days may be good for those somewhat familiar with Unity and wanting to see what it does from the previous versions. But 60 would be better for those not familiar with Unity and the way it works, which seems like most of those (us) trials are aimed at. Probably less headaches and work for support as well.
I stand pat. 8)
The trial length used to be 2 weeks, which seemed plenty to me, and that was before I was familiar with Unity.

If you ever developed with anything you need at max a week to get a basic game going.
There are users here that have had running prototypes online after 3-4 days even.
The Unity tutorials as well as the sample projects make it pretty easy to learn the technology and the option of JS and C# make it possible to near anyone to “just do it”
If you need more than 4 weeks for evaluation, ie toy around and/or create a basic prototype of your idea, then something went wrong.
Unity is, beside Game Maker 7 and Multi Media Fusion potentially, one of the by far easiest game development environments at all especially with the resources and documentation (over 500 pages for the documentation itself and countless pages in the script reference) that you have access to and the great community here
Working the tutorials, especially the 3D platformer tutorial, I think give a really broad scope of what Unity can do in less than a day. 30 days for an almost fully functional version of Unity is pretty fair.
But if something happens and you really need an extension, we sometimes grant them. If we’re in a good mood.
(jest alert)
OK thats it. Lets take it outside. :twisted:
Or at least to the gosip section, in “Me, I’m a “60 dayer”
