I'm not sure if this is the right place but any way, when i try to load my map in co-op it starts to load semper fi instead of my map and then it crashes. It seems to default to co-op semper fi instead of my map and i can't change it to my map because I have ugx installed.  Any help would be appreciated.

You need to open raw/ui/main.menu and edit the top lines of the file to be correct for your map.

Then rebuild your mod.ff and use the project mover to update your map folder etc etc.
