When I try to run setup.pl I get this error:

Setup has determined that you must manually edit the paths to Settings.pl or other core files. If you need help, contact E-Blah technical support.

The following may help you figure out what your paths are:
Document Root: /
Script name: /home/www/tslforums.awardspace.com/cgi-bin/forum/Setup.pl
File(s) Not Loaded: ./Settings.pl
Reason for failure: No such file or directory

Before I go in messing with things, can someone tell me what needs to be changed?

In setup.pl, try changing the following line:

     InstallConfig() if(!SetupLoad('./Settings.pl',1) || !SetupLoad("$code/QuickCore.pl",1));

to:

     InstallConfig() if(!SetupLoad('/home/www/tslforums.awardspace.com/cgi-bin/forum/Settings.pl',1) || !SetupLoad("$code/QuickCore.pl",1));
