Never mind...I just deleted the entire thing and installed the upgrade forum from the Fantistico scripts. I lost all my files of course, but the forum is back and upgraded to the 2.0.11, so hopefully it will prevent future hacks of this nature
I have a backup of my forum, but I am afraid to use it for fear it will revert it to the previous version and not the 2.0.11...I am a complete incompetent at almost everything to do with php.
