You are suspended for inactivity, you can unsuspend yourself through account panel (
http://x10hosting.com/panel.php).
Once you done so the account unsuspension will be placed in the queue, and the system will deal with it when it comes to your entry in the queue, this may take a couple hours if there's a long queue.
If your account is still unaccessible in 12 hours, post back and we'll investigate further.
