I have used PDFCreator happily for years on XP. When installed on Windows 7 it worked for a few days, but now gives the "Unexpected error; quitting" message early in the print process. Unistalling and reinstalling made it work for one more day.

I have made all the Registry fixes suggested elsewhere, and I've reinstalled the VB6 OCX successfully with a download made by Microsoft in 2005. Any other advice? I use PDFCreator quite a bit and it pains me to think of looking elsewhere.
