CMS Made Simple Forums

I installed FrontEnd User and Custom Content and am getting the following error when I try to access the admin screens for FrontEnd User:

Line: 56
Char: 3
Error: Object Required
Code: 0
URL: http://dev.filtercouncil.org/newsite/ad ... ntEndUsers

Any ideas, I am pulling my hair out on this one.
Thanks

*Sighs* I've got a few bald patches now too, but in case you didn't solve it it looks like a memory exhaustion problem. Upping the memory limit in php.ini seemed to do the trick.

Nice looking site by the way.
