Problem after update to the unity 3.4.1

I update my unity to 3.4.1 and my old project don’t open anymore, so i unistall, and install old version again, and this not solve the problem! I Get my old backup, and even this don’t make unity open the project right!

I have something to do?

Some help guys?

We’re not psychic, if you want help you’ll need to provide enough information so we have at least an inkling of what’s going on. What OS are you using? Did the project work in 3.4? What exactly do you mean by “don’t open”? Are there error messages, if so what are they? etc. etc. etc.

In the future I highly recommend you install new versions of Unity separately and keep separate project folders for each version of Unity on your system. That way if a new version of Unity has an issue with a project you can always just launch the older version of Unity and the old version of the project without even blinking. I’ve been doing this since Unity 2.6 and have been recommending others do this just as long.

Sory bigkahuna for my despair! I just don’t know what to do!

My OS: Mac OS Lion 10.7.1

When i rename my project folder, and try to open the project i get no error messages, just unity stop responding.
if i rename the scenes folder too, the project open, but when i try to open any scene, unity stop responding again

Even if i back to old Unity i can’t open any scene of this project anymore.

Any idea?

OS X 10.7.1, eh? Hmmm… I seem to remember someone else having problems with the latest OS X. I’m mostly Windows now a days and my MacBook Pro is running 10.6.8 so I’m afraid I’m not going to be much help. Perhaps file a bug report and hopefully someone at UT (or another OS X Lion user) will see this and jump in to help.
