there is nothing we can do about stolen keys, and we will not lift bans for stolen keys as to we would be giving hackers a way to still play in our servers.
Also just a little fyi there is not a key generator out there that uses keys that were not stolen by a second hand program (second hand programs meaning profile backups, game optimizers, basically a virus on your computer).
I would suggest you reinstall your whole operating system before you enter in any new keys.
