I've tried all of my other options, and haven't been able to register my CD key.

If everything else has failed, your last option is to mail in your CD key and have us reset it. This is a slow and potentially expensive process, and we don't recommend that you do this except as a last resort.

Please note that when we reset your CD key, we'll remove it from the account that has currently registered it. In addition, please note that we are unable to reset CD keys that have been banned by VAC.

To have us reset your CD key, please mail us the following (by postal mail, not email):
- The original printed CD key (ie, just the jewel case or cardboard sleeve with the CD key printed on it, not the whole package, and not the CD itself)
- Your email address
- The Steam account you want the CD key assigned to

Send your package to:

We are unable to return anything you mail to us.
