Error when trying to activate a plugin

Hello!

When I try to activate a Content Protection plugin I get the following error:

Fatal error: Cannot redeclare constr_menu() in /mnt/target05/925084/928857/www.clnconsultoria.com/web/content/wp-content/plugins/WPCCP61114UNCOMPRESSEDSSU/fwpconsec.php on line 22

Thanks a lot for the help!
