Campaign Problem

[Wishbone]

Can somebody please help me.
I just had my butt kicked in the" Fortress Europa " campaign, so decided to have another shot at it, but when I try to start a new campaign I get this message."NO BRITISH HQs/SQUADRONS CAN BE PROPERLY PLACED WITH SPACING 2 GIVEN THE CURRENT SQUADRON DATA AND FRONT LINE SHAPE".
Ive deleted the saved game file in my documents, but that didnt work. Ive also changed pilots nationalities, but get the same message.
So has a last resort I uninstalled then reinstalled the game. Guess what I got the same message again. Ive done this twice now and its still the same.       HELP
