Hello, there is no trial or free version for Unity3D 5 Beta 9? I downloaded it but i can’t open it because i have no key. My Question is, why other options (30day trial) are disabled.
I don’t have Unity Pro. So i can’t have Unity3D 5.0 free version;
That’s correct, it’s not out yet. Trial will come when it’s released. If you subscribe or purchase it, you will be given a key.
It’s a beta. It’s only open to paying customers right now.
Aouts! ok!
As a hobbyist and student, i can’t buy it. :(. Anyway… i am waiting for official release 
As a student you can get a student discount
True.
Atm i am not going to develop games. So, it will be waste of money.
Unity Licese has expiration date? it is for 1 year or forever?
There is no expiration date for purchasing a Pro license. However, student licenses are to be used only by students.
Edit: Actually, if you buy the “One Year Suit License for Full Time Students” it IS limited to one year - http://www.studica.com/nor/en/unity/unity-pro-5-game-development-student-license/u5pro-2014-cs.html
