Okay, so a few days back I bought a pre-owned copy for TF2 from GameTraders. When I got home, obviously, I tried to install it. I got a duplicate CD Key error. Fuck. I messaged Valve regarding the matter as one of their 'Help' topics are 'Duplicate CD Key Errors'. It said they could reset it to my account, so I asked them if they could. Me: "Hey, I bought a pre-owned copy of Team Fortress 2 from my local GameTraders and It comes up with a Duplicate CD Key Error. Could you please reset the CD Key to my Username? Thanks!" -attachment: CD Key & Receipt- Valve: "Hello, Thank you for contacting Steam Support. We do not reset CD keys from auction sites or in cases in which the game has been resold or given by another individual. The buying, selling or trading of Steam accounts/CD keys is a violation of the Steam Subscriber Agreement. I recommend you return the game and inquire about a refund." That's BULLSHIT! Don't tell me about how selling a CD Key is a violation of their SSA! The previous owner already did that and now he's getting off scott-free!?!? FUCK THAT! So I reply with: "What? But I bought the game from the store! I don't see what I've (or the store for that matter) have done wrong! The other person is at fault for registering the game under his account and then re-selling the CD to the store because he 'didn't need it'. It would be much appreciated if you would reset the CD Key as I, and the store, are not at fault." And now I hope for the best. What are your guys' thoughts on this matter? I'm off to go play GvGN+, so, Cya's!
