You are auto-banned for cheating.
Try to contact the game admin at gameadmin@gatewars.com or via the forum at: THE GAME ADMIN SECTION if you do not know why this has taken place.

EDIT: email sent to gameadmin@gatewars.com
EDIT 2: My account is still showing as rank 96 and on PPT on my stats page. It is NOT rank 0.
