When CS3 is attempting to load, what is the last entry with regards to the .dll's. You have to look closely to see them go by. I've found that setting up a video camera to shoot the screen can help. Just pause your tape at the point that it fails, and see which .dll it's struggling with.
If you have many VST plug-ins, one of those would be a likely candidate. Do you have any Audio programs, like Native Instruments? PrPro will survey your entire system, looking for VST's. Unfortunately, there are some that it cannot use. These usually give only an error message that appears the first time that PrPro tries to load that one. You never see that message again, even though PrPro still cannot use it. Most are fine and PrPro knows that it cannot use the VST. Others, will cause exactly what you are seeing.
Now, that is not the ONLY reason for such behavior, but I want to rule out VST's first. Still, that last line will give you a clue. It could be that .dll, or the next one (whatever that is), that is the issue. The .dll could be corrupt. If it's an Adobe .dll, your updates should have fixed it. If it's someone else's, then it could be tougher to track down. If you can get the name, then a search should tell you which folder and which program has that .dll.
Thank you so much Hunt, that was just the problem, I moved my program files/VST plugins folder temporarily to the desktop and premiere opens fine. When I move it back the problem recurs. For the time being I can do this, and I will scrutinize which dlls are to blame later. I only use the VSTs with FL studio and Ableton live and would not need them with premiere anyway.
Where does premiere scan for VSTs? is it just the program files or whole computer? It certainly doesn't seem to look on the desktop.. I couldn't find anywhere in preferences to change where it looks.
Many thanks again,

Pretty much the whole computer. Actually, I did not realize that it did NOT look in Desktop, so I learned something new, thanks to you.
Eddie Lotter (keeper of the PrPro Wiki) was working on a script that would "blacklist" certain VST's from PrPro. I believe that he had it up and running, but then found that it did not function in Vista. Not sure what the disposition of that is. You might find more info on the PrPro Wiki, under VST's.
Good luck, and thanks for reporting about Desktop. I will remember that and refer others to that trick!!!!
