Sorry you had this problem Joseph. I think something might have gone wrong with your installation.  Sounds like the right airfile didn't end up in the right folder.  Or maybe the cfg file was overwritten in some way after you edited it.  I spent a lot of time tweaking the flap lift so that there would be around 1 to 1.5 degrees of pitch at VREF +5 on a flaps 30 approach.  The mod is only for the 727-100 model.

I checked the download and the correct air file is there.

I wonder as well this could be connected to the different Captain Sim 100 model variants? I have never used the one with winglets or anything other than the basic 100. I should probably look into the question of variants and the operations of the ACE utility.
