After updating to 11.26, I've been unable to use some of my add-on aircraft. The game crashes with the error (this is one example but the error is similar):-

An airfoil file could not be found! The airfoil paths I checked are listed below!

Aircraft/Custom Aircraft/DHC-1 Chipmunk/airfoils/Chip010.afl

Airfoils/Chip010.afl

Get that foil in place if you want to fly!

I've double checked the folder referenced and the files exist so not sure where to go from here, they worked fine with 11.25. I've tried removing the aircraft, re-downloading them and copying them back again but getting the same error. The log doesn't show anything more than the above, except it has the following line immediately after the above error:-

0:01:03.119 E/SYS: | (aifl.cpp:238)

I use the Steam edition and have run the file validator, no files were flagged. I only have five custom aircraft and the above error shows on three of the five, the other two run fine as do all of the built-in aircraft. If I try loading the aircraft into Plane Maker I get the following error (again, this is one example but a similar error shows for the others):-

An airfoil file could not be found! The airfoil paths I checked are listed below!

Aircraft/Custom Aircraft/DHC-1 Chipmunk/airfoils/Chip010.afl

Airfoils/Chip010.afl

I am switching it to a NACA 0012 symmetrical now so you can load the ACF to attach the proper foils!

Any ideas? I don't know what to try next. Log and screen snips attached, showing both the errors and explorer window showing airfoil files in place. I've only just re-installed X-Plane and took ages setting up the way I like it so would be gutted if I need to do it again.
