o.k. heres the deal. i bought this computer from dell about 3 years ago. since then i have moved. I had to reformat my hard drive and reinstall windows xp. i lost the serial number card to it and called dell up. No dice its been 3 years and they wont help. call up microsoft. call microsoft and of course i get a computer with no choice to talk to a person. The computer doesnt even give me a choice for my situtaion. the choices are registering my version of windows or buying windows. so i get a serial number from the internet. then it installs and tells me i have to go register. i go register and it doesnt work. so i go and get a hack and get around the problem. now i have a program that wants directx9. will i have problems if i install directx9 or should everything be ok? btw never buy from dell. they wouldent help me and i come to find out that my sound card is one only made for dell and dell doesnt have the drivers anymore neither does the card manufacturer. I do onw my version of windows xp i just lost the serial number to it. before people jump on me think of it this way. you buy a car and if you lose the keys does the dealership tell you "im sorry your going to have to buy a new car"
