To Administrator-Problems with Gamersgate version

[Maluzu]

I got my game from gamersgate.com

I have had three issues thus far,

1) I am unable to use the english (aka Atari) version of the map editor, it will not detect an installed game...
2) I am unable to play online vs other people, conflict of game versions. (even though we both are running Version 1.0 August 2007)
3) I can not uninstall the game... I tried to uninstall the game using add/remove programs... here is what I get:
Internal error: Cannot find utCompiledCode record for this version of the uninstaller

Also... I tried to install FW from gamersgate at another location that I frequent often, and it wont let me. I forget the exact error... something about being invalid. I paid 39.99 for this game, always running into issues. Still fun, but I need to keep overcoming barriers
