CD key already activated
this may possibily be a steam-related issue, so incase it is, i have already posted the same question on the Steam forums.
anyways...over the weekend i was at a flea market with a female friend of mine and saw a copy of Sin for sale for like $2. figuring itd be a fun game for her to enjoy, i bought it for it. once i installed it, the installation asked for the CD key (at this point, i have to input the CD key into a Steam menu. i input it exactly and it gives me a message that the CD is already activated on another account and therefore is invalid.
this is a really stupid "security" feature to have implemented for this exact reason. this game is what...7, 8 years old? pretty much FOREVER the game can only have 1 owner? thats just ridiculous.
is there anyway i can get a new CD key for this copy of the game?
