boombaxx. I'm not sure which European campaign you're referring to. It's not likely that I've tried it myself. Assuming the campaign is installed correctly you have to select the correct Nationality from the Campaigns options. I assume this is either British or German but this is not necessarily the case. I would think this would be mentioned somewhere in the Readme instructions. When the correct Nationality is selected you should then be able to add a pilot. The new campaign should be listed on the menu.
