? Using Downloaded A/C in CFS3 Campaigns

Hello Everyone,
I hope that you folks will come to my rescue once again. I've downloaded a number of planes from the folks over at Mudpond and I've unzipped them into my aircraft file. I'm able to use each and every one in Quick Combat, but for some reason, the planes don't show up as possible selections for campaigns. Now here's the interesting part...when flying a campaign using the stock aircraft supplied, the labels assigned to the opposing aircraft identify them as being one of the downloads! So...anybody got any bright ideas about using downloaded airplanes in campaigns? This worked just great in CFS2.
Thanks,
Boxer
