Alpha Bleu Ciel Corsair errors

Due to a blown h.d. I am replaceing my favorite add-ons. I just re-downloaded and installed the F4U-7 Corsair (P18 Vintage FS9) and saw a new fix. When I tried to install it, I got a message that there is an error in the AIR file but I cannot find a way around it. I suspect it's an adjustmemt to the P-factor and torque sensitivity. Anyone got a solution?
