Guys, I've got Acceleration ordered, and should have it here in a few days, but in the meantime I have a couple of real newb questions... First, I've already installed SP1 and, unfortunately also SP2.. I read in the forums that you can't install Acceleration over SP2.. Is there a way to uninstall SP2 without completely un/re installing FSX? Second, I have added no extra or modded terrain or scenery. I have, however, added a considerable amount of new aircraft, both free and payware. Will I lose these planes when I uninstall SP2 (if possible), or when I install Acceleration?
