i recently DLed the Flyhonduras toncontin scenery and its as though the airport is places wrong or something.. the planes dont follow the taxi way and they land on the side of the runway almost off of it.. and when i start the flight there... its parks the planes almost inside the builiding... anyway to fix this?

I think you have a wrong AFCAD file. Probably you didn't delete the AFCAD file of the addon scenery and now you are using it with the default scenery. Check it with Lee Swordy's AFCAD program.Good luckGuille
