I have tried reinstalling many times. I even reinstalled all of the CS4 programs jsut to make sure but still no luck. When I start up adobe Pr it will load a full screen window (all white though) and then crashes
I am currently running on Windows Vista 64-bit
and I can say my computer is more than enough for this program it is not lack of hardware.
Reinstalling would suggest that the problem is not with PR alone, but more in some incompatibility with other system components. When you say crashes, does it hang on the white screen, does it disappear, does it hang the PC, what happens?
First check out this link and specifically the second part.
