ok so here's what's going on. i borrowed a game from my friend to try it out and play it online a little and i liked it. so i went out an bought my own copy. i uninstalled his and when i tried to install my copy i get a message saying another version is installed and that i sould go to my add/change program list to get rid of it. i have done this and even used jv16 powertools to fully delete all the reistry keys and anything else and yet i still get this message. is there anything else i can do besides reformating my entire computer?
