If you don't remember your Account ID, you can check it from the "Account Overview" section after you login to your rapidshare account via http://www.rapidshare.com --> `premium zone` --> `premium-zone login`. Your Account ID should only be formed with numbers, please don't submit your username (login alias) instead of your account id. It's not possible for us to reverse the adding Rapid process if you provide us a wrong account id.
