I have 4.09 installed with HSFX. Whenever I select an offline campaign flying the Spitfire MkI using Cannons Channel map I encounter the following problems. On loading of a mission I get an error message "afd error" when the mission initially loads. When sitting on the ground ready for take-off the terrain appears to wobble rather like jelly and no matter what handling technique I apply the Spitfire noses over half way through the take-off run. I have not encountered this problem with any other aircraft type, Hurricane, P51, Bf109 etc. The only way I can get airborne is to use the auto-pilot. Once airborne there are no other problems with the simulation. Can anyone provide me with advice on how to rectify this as my self esteem is taking a battering..
