yeah i realise now it was a stupid thing to do but i couldnt be bothered downloading it and i wanted it legit. it says duplicate key and valve wont accept a picture of the reciept from a used seller etc etc in my defence - i didnt realise the key could only be used once - i have gta iv and you can deactivate the key when you uninstall so it can be reused thought it was the same with steam games, but anyway... so now i have the discs and i'm not sure what to do next. i've emailed the seller that the discs are pretty much useless but i just wanna at least play the games over the weekend till the seller gets back to me with a refund or whatever. what do i have to do to get the games installed? theres a lot of different tools on here and i dunno what i'm doing. any help appreciated.
