MISSION LOAD: 'Training-1.fs2'This is actually the first training mission, which is supposed to be at the beginning of the campaign. I think what's happening is that the pilot conversion (3.7.0 uses a new format for pilot files) is not carrying over campaign progress or available weapons, so you're now back at the beginning of the campaign with no weapons.
You should be able to "fix" this by going to the campaign room and clicking "restart campaign." You'll have to play act 1 again, but at least you should have weapons.
