Unity Freezing

Just purchased a Unity Pro serial number. When I open unity to enter the number, the app just freezes. I tried uninstalling and reinstalling, but that didn’t help either.

My OS is Windows 7 x64.


Someone in my work had a similar problem and it was a problem with his videocard driver, he updated it and Unity had exaclty the behavior you describe, so he says that he downgraded the driver to de one that comes in Windows by default… good luck with that =)

Run Unity as admin, should fix the problem, internet activation takes a minutes or two but it should work
