Within the last week, I upgraded from Windows Vista to Windows 7. In my Windows Vista version of the Media Center, I had nearly 60 CDs that I'd ripped and kept in my Albums collection. This evening, I found that my Windows Media Center shows me having 22 albums, most of them intact, a few not, and the 22nd album containing 600+ tracks... basically all the other missing albums lumped into one. Everything appears to be correct when I access them through the Media Player, but completely ruined in the Media Center. Is there any way I can restore my original albums without deleting my whole music collection and starting from scratch??!?
