I have moved and don't believe I have changed anything in my computer relating to FS. I am now having trouble getting any aircraft to take off. I have reduced the fuel on board, and added flaps before takeoff roll. All the planes do is keep running along the ground without any upward movement. I thought it was only in FS2002, but I tried FS2000 and the same thing occurs.
If I have to reload the programs I am worried because I have a lot of third party planes, gauges,airports and scenery which I don't want to lose and have to reload.
Anyone with a suggestion will be greatly appreciated.
