I really, really need help with this as soon as possible. Waiting hours for support just isn't an option. So, how do I delete an account to make room for a new one? NOT DELETE A KNIGHT. I mean an actual account used to sign in to SK. This normally wouldn't be a problem, except they are denying me access through my new account. So, please answer quickly.

NOTE: This is because of too many accounts being on one computer, and I'd like to know how to bypass this account number or remove existing accounts WITHOUT buying a completely new computer.

NOTE: The reason I'm doing this is to have a non-steam bound account.
