The only way to reset your account is to have it terminated, and then for you to sign-up again.
If you want me to delete your account, make sure you have a backup then post back here.
Account Unsuspended.
Log into cPanel and find the "File Manager". Click it. On the window that pops up select "Home Directory" and click Go. You should then be able to see the "public_html" directory, and you will be able to edit the files.
Your cPanel URL is: http://sgvso.exofire.net:2082 (just add the ":2082" onto the end of your site's URL.)
BTW: how many free accounts do you have? I ask because the URL you posted is different to the URL of the account that is linked to your Forum user.
You will need to put the ad-code (You can get it from the AMP) in the header.php file. If you place it just after the <BODY> tag you should not have any problems.
