If so, very sorry about that. It only affects 1-2% of players, but it's certainly annoying. We're trying to figure out the cause of it (basically, we get a false negative when checking the Steam ID for game purchase).
In the meantime, please email [email protected] and request that an account be created for you, and tell us what username and email address you'd like on the account. We'll get it done within a few hours (except when we're sleeping). Thanks for your patience.
