I have been using GR for a while, and have the 1.4 version installed. I"ve tried several Mods, and the kits and characters all work fine. However, when I try to start a campaign that comes with the Mod, I get some sort of crash,and the desktop apears. I am not sure as to why this is. But I have not been able to play any of the campaigns that came with several mods, and They sound So awesome (Besides, one can play the original campaign only so many times...maybe not...)
