Since updating to 5.02, PPCS5 on W7 throws up errors when capturing from a Canon XM2. Had no problems with 5.01. And, don't have a problem using PE8 - in fact I have to use PE8 to capture because PPCS5 refuses to play ball.
So, what's the simplest way to roll back a version? Bearing in mind I have the Master Collection installed.
Before rolling back , I would search for a solution to the issue a little while longer.
Its no big deal to capture meantime in the other workflow and there are no guarantees that rolling back will fix the issue ( ie. it could be something else).
Yeah, going back to 5.01 is probably not the right way to go. I agree that finding the problem is probably the right way to go about this.
Try the standard stuff:
upgrade graphics driver
clean media cache
If that doesn't work, here's what I would do.
I would launch the uninstaller for Master Collection and then I would uninstall/reinstall JUST Premiere Pro. Once you do that, then run the updater to get Premiere Pro back to 5.02 and see how things go. Failing that, then I would contact tech support and this forum for additional suggestions.
Hope this helps,
