Windows 7: GFWL Game Save Troubles

Hello,
I just installed Windows 7 on an extra HDD. I normally use XP, so I wanted to try some games out to see the DirectX 10. Two of those games are Resident Evil 5 and Red Faction: Guerrilla. On both games, I used an offline Windows profile. When I copied the saves over (from the Documents folders of each HDD) and try loading them in the game on 7, it says the data is corrupted. I thought I could fix it by making an offline profile with the same name, but no luck. Did anyone else here have this problem? What fixes do you guys recommend?
Thanks for any help!
