Re-downloaded all files, but still no change.
Assuming you mean the option to change sides in the "War Patrol" section, yep, just tried it, but still same issue.
All I see in U-Boat Campaign is "Into the East" and "Fortunes of War".
What's the bet that someone will point out the worlds most obvious solution to this that I just can't see...
Should also mention I am running RSRDC. Both files needed are modded into SH4 1.5 prior to OM as per instructions on 1st page. No idea if this info will help at all...
