right this is really beginning to irratate me now, i have a genuine copy of windows vista home premium 64-bit which i bought quite a while ago from OCUK, it was new and unopened. i have only ever installed vista on one occasion, recently after a series of ridiculous power cuts (multiple cuts in the space of an hour) my hard disk was well...screwed basically. got a samsung spinpoint 750Gb disk and installed windows vista as normal, now whenever i try to activate vista online it says my product key is already in use? how on earth are you meant to activate your product short of phoning up a bunch of useless yanks...? thanks for any help cause its really bugging the hell out of me
