I played through the GDI campaign using modded units and had no problem, but when I tried to start the Nod campaign I get this error every time I try to start a new mission. If I remove all changes from the game it runs fine, but if I attempt to alter anything (even just the price of a unit) the mission won't load. I have re-installed both the game and TibEd, but that didn't help at all. Any suggestions?
