hi, i've been running my windows xp since november of 2005 with no problem. i purchased it from a reputable retailer. it's an oem version, since i built my own pc. last week i got a message to install an update from microsoft about wga or something like that. i postponed it. this morning i got a message that my xp is not genuine, "you may be a victim of software counterfeiting". then i ran wga diagnostic software from ms. it says "geographically blocked PID". anybody had this problem before? i've heard that this wga is screwing up people who have had legit copy of xp. how do i go about this? who do i contact. are there any phone numbers for ms? thanks.
