Crash after Update

I recently updated to Unity 5.2.1 from unity 5.0.2. but every time I try to open up a project I made on unity 5.0.2 it will wait about 1 - 2 minutes then the Bug reporter will pop up. Even the Standard Asset Example Project won’t open up! Before I updated I was working on the project at it was working perfectly fine. Please help.I have the 32 bit version of Unity.

Im having this problem too. Happens all the time but mainly after I stop playing my scene. Submitted a bug report to Unity but no reply yet.

Anyone else having this problem?
Any solution?
Am I able to downgrade seeing as its not a major change?

Thanks
