Error message on BuddyPress signup page

When I go to my login page:

It appears that the full signup page does not load and an error message appearson the same page:

Fatal error: Cannot redeclare class AYAH in /home/jewelnet/public_html/wp-content/plugins/anti-splog/includes/ayah.php on line 44

I have deleted and reloaded a fresh download of the buddypress plugin but that does not appear to help.

Please tell me how to proceed, I'm out of my depth here LOL.
