Wings of Prey and Wings of the Luftwaffe

[beefsteak]

I have had these for a couple of years and finally got round to finishing the first one, I opened up the 'add on' "Wings of the Luftwaffe" and went through the process of letting it load up. There is a code in the box but nowhere to input it!. I click on the new WofL icon on my desk top to load the game, scroll through to the WofL , click on that and it tells me i need to buy it for 30 yums??!!

If it try to log in to Yu play, It's all in Russian no matter I have it set to English.
Ant body know what's happening here

Thanks
