Vantage kicks me out!

I have a test database that I upgraded from 3.0 to 5.20.305. When I try to run any reports Vantage kicks me out. When I try to run Report Builder. It pops up for a second and closes and when I try to run results, it takes about 10 minutes to open. I tested each step of the upgrade and everything worked well until 5.2. Does anybody have any Ideas?
