Library Favorites?

Been using the RC1 for some time now. Love it, cant wait for the full on release. But in my "wisdom" i used a tweaking utility to toy with my settings, and now i cant use my Favorites under Windows this i mean the virtual folders thing, not my IE favorites..those are fine (they could have named them something else to avoid confusion?) My big problem is that my only backup of Win 7 is scratched and therefore unbootable. and of course, since Win 7 is no longer downloadable from MS anymore...i cant simply do a repair install. Any help here? ty :)
