Looks like you are running a mod that is a bit out of date. With v1.16 the German bitmap folder is now Major_08 and the Italians are Major_09. If you rename the folders accordingly in the MOD it should resolve the issue for you.
1) Remove the folders Major_09, and Major_10 in your Campaigns\_1939 Storm over Europe\Bitmaps subfolder, i.e. the ones you just copied over, you won't need these.
