Security Assist /PowerCMS Conflict? - Fatal Error

I swear I can break stuff just by thinking about it.

I had a fully functioning site late yesterday, after sorting out the paths problem with Security Assist, but after adding the developer code from CMS to the regular pages, I am not able to access any of the protected pages (in an 'admin' directory in the site root) because of an apparent conflict between the CMS' and Security Assist's 'Helper_PHP.php' files.

This is the errorI get when trying to access any of the protected files in the admin folder:

"Fatal error: Cannot redeclare wa_authenticateuser() (previously declared in /home/users/uks45031/html/katelissauer.com/WA_SecurityAssist/Helper_PHP.php:10) in /home/users/uks45031/html/katelissauer.com/cms/WA_SecurityAssist/Helper_PHP.php on line 48"

No code has been changed in any of the Security Assist pages or folder, or on the protected pages, since it was working beautifully. Only the developers code has been added, which seems to have caused the problem.

The CMS folder (cms) and the Security Assist folders are both in the root directory.

Should I just I just redirect the CMS page includes for the Helper_PHP.php file in the SecurityAssist directory in the 'cms' folder to the SecurityAssist directory in the root folder?

Help on this would be greatly appreciated.

Thanks.

P.S. - I can log in to the CMS without any difficulty.
