now i know there are a few vista topics but i havent read any with this problem yet. sorry if i missed it. anyway, has anyone had problems validating vista? it seems a common problem talking with microsoft. my new rig worked fine for about a month. than suddenly it says my copy is unvalid, btw microsoft says copy is good. Ive dealt with 3 diff levels of microsoft support so far (Dante's inferno anyone?) anyone else have any issues like this? thanks:)
