Just Flight AFCADs...

I own the Just Flight British Airports East package. I'm very happy with it, except for one thing.
I like to create Ai for my airports but I've has difficulty creating AFCADs for the bases in the package because AFCAD doesn't seem to read them properly and I can't find any proper AFCAD files for download anywhere.
Can anyone help me with these problems?
