Upgrading Unity 3.2 Problems

Ok I just upgraded/updated to Unity 3.2 and now my game has screwed up. Is there anyway to downgrade back to Unity 3.1 or 3.0?

Ok well i downgraded back to Unity 3.1 but it seems that I will have to start over since none of my data was saved or put back

To downgrade Unity on OS X, you simply have to remove Unity from your applications and install the older version again. I still had the previous installer in my downloads directory.

Also make sure you don't have the DMG file of the other Unity version open, or you may accidentally install the newer Unity again.
