Hi all, hope someone can help. I recently sold an old copy of Counter Strike: CZ that I could never get to run on my PC. Well stupidly I forgot about the fact that it had been registered to STEAM so when the buyer tried to register it, it said that the CD-Key had already been registered. I'm pretty sure I remember my username and password so is there any way I can unlock the CD-Key so it can be re-registered or transfer the registration to the games new owner? If not I think that i'll just refund the guy as it is likely to become a bit of a hassle. Thanks.
