Update to forum Profile FAIL

I’ve tried sending this to the webmaster email address and its bounced. What is strange is that sometimes the profile update works when I go back to look at it, sometimes it doesn’t. I always get the error message though.

A fatal error has occurred: Died at /home/slowtwitch/forum.slowtwitch.com/cgi-bin/admin/Plugins/GForum/SlideShow.pm line 218.
