Encore CS3 cannot open CS2 project: folder cannot be found

Question

I created a project in Encore CS2 under Win XP, and when I try to open it in CS3 under Vista, I get an error of
Cannot open project; The folder for this project cannot be found.
Disregarding the fact that I haven't changed, moved or deleted any subfolders or files and the drive has the same letter and label as before, why the heck doesn't Encore at least give me the opportunity to direct it to the correct folder? I can do this easily in almost all other applications, like InDesign or Dreamweaver. Shouldn't this error have come up in the first few days of beta testing? (Uh, it
was beta tested.....right?)
I tried looking in the ProjectPrefs and ProjectWorkspace xml files, but they don't have any folder info. Searches in the knowledge base, forums and newsgroups have turned up nothing. It seems my only choice here is to recreate the fracking project from scratch!

>(Uh, it was beta tested.....right?)
No. It wasn't. The Encore team is so good at coding and spell-checking that the Product Manager and the Director of the Production Studio project both felt that beta testing was not necessary this time around.
It's really pretty impressive that so few bugs have turned up in real-world use considering that both internal and external beta testing was shelved for this release. The additional resources that would have been used to test the app were sent to the Photoshop team to ensure that the CS3 release of PS was flawless.
