>Removed CS5 trial, restarted, reinstalled
Well, since the trial puts a secret code in a hidden place to insure that you can't re-install the trial after the 30 days, I think that means you are totally out of luck
The trial now "sees" that it has been installed before, and it will not run again
That doesn't seem right, because the other programs in the trial (I downloaded master collection just to see what all was new) still run. It's only Premiere that's having this issue.
I actually got it to load finally, just by pressing random keys. It seems I just can't "see" the splash screen... it's not appearing for some reason, even though it will still accept keyboard input.
Try opening Premiere holding the shift down.
