I tried to eliminate a downloaded plane from the planes folder in G3, after I deleted it when I go to select new planes I get the message "the aircraft failed to register, this aircraft is based on one that you do not have, It may be in a add-on disk", it did not give me this message the first time I added it and I was able to select it and fly it. I put the plane back in the planes folder and tried to delete it in G3 under "select Aircraft" put it is not there now though it was there the first time I added it. How can I get rid of it and not see that message everytime I select a new plane?

Thanks,
