Okay guys i really need help fast.i had a HP Pavilion T250i with two HHDs each of 80 GB,a 2.4 Ghz P4,768 mb of RAM,and Win XP Home.I recently upgraded to an X2 4200+ with 2 gigs of RAM.The problem is,while trying to activate my copy of XP Home with the product key of my last PC,it does not accept it.The message i get while trying to activate the copy is "Wrong Product Key",and it prompts me to retype the key...but no amount of retyping helps,i always get the same msg...I also tried callin those phone numbers to activate it by telephone,but neither of them ever get through!! Any suggestions? :huh:
