I've tried adding in several new locations into CFS2: Pearl Harbor, Normandy, the Battle of the Bulge, etc. Everytime I add in the scenery files, the microsoft stock weapon loadouts disappear--they can't be found in the loadout list and are not on the plane while flying.
As far as I can tell, the only way to get the weapons back is to reinstall the whole game.
I'm running XP Pro on an older machine. Does anyone know what might be causing this?
