I have both xp x64 and xp home. I installed x64 not knowing that it's a bastard stepchild that has compatibility issues with everything. Is there a way to smoothly transition the two without having to reformat and lose everything on my hard drive? Edit: just out of curiosity what are the benefits of using x64? And what problems will I commonly have if I stay with it? I've already had issues with itunes and windows live messenger.
