I installed the hack and I have tried everything, but I can't get past this error. I can't find the problem anywhere.
Parse error: parse error in /home/teamacid/public_html/topposters.php3 on line 45

This is my topposters.php, all my files are .PHP3 so I changed this to .PHP3- Could this be the problem?
