It worked marginally about a month ago - was picky with what MP3s it would use even then. Would a system restore change EVERYTHING, even quickbooks files to that date? Not even sure if I have that set, as I'm usually a Mac person, so most windows system settings are greek to me. Just about the only thing I use this PC for is P2E and quickbooks. Have been using P2E for at least 2 years, so I'm pretty well versed in the in's & out's of it, so that's why I'm stumped as to this current problem.
