I hate to go back on saying "i wont change this thread anymore", but it will indeed be the last time, because I won't be needing to work on this file anymore. It seems the new devs have solved the problem:

Update April 12, 08: The new gfire devs have a new version in (unreleased at the time of this post) beta testing. Please see their new site for the most up to date gfire_games.xml and gfire version.http://edhewitt.co.uk/gfire/ as such, this post (and the section on my site) will no longer be updated.
