durring a restore of windows xp pro, after compete restore using win cd it comes to the log on screen with one user profile, click on profile to enter windows and it say could not verify licence, and prevents windows from opening. tryed restore twice with two different oem windows cds. the os was a genuine install from store bought win xp pro disk on home built pc. is this just a mismatch of windows xp cds or somthing like a installed virus program intefering. the pc owner was randomly deleteting stuff all over the pc and avast was deleteing windows files that it thought were infected but werent. i need it to start, many gigs of info on this guys computer i cant loose.
