Tried what you said:
1. downloaded script and inserted into the folder
http://www.modracer.com/cgi-bin/rebuildmems.cgi 2. Opened
http://www.modracer.com/cgi-bin/rebuildmems.cgi in a browser and it gave me this message:
STOP! Please close your UBB first in the control panel.
I'm sorry but I'm lost...
