I clicked Try Again and it just popped back up. I click Force Quit and it quits obviously. But when I click Cancel, it opens up the Unity project selector thing. But the problem is, this is all that happens:

I had similar problem long time ago. I added permissions to folder with unity for my windows profile and it worked.
