Hello,
I've been flying this wonderful aircraft for a few years. Version 3.14. I'm migrating to a new computer. I installed 3.12 and it works fine. Then I updated to 3.14 but the zip file is missing the air file and FSX complains it can't load the flight model.
If I change aircraft.cfg so sim=Douglas_DC3_v1.4, it flys, but its the 3.12 version.
The file seems to be missing from the 3.14 zip files. I've downloaded from here and another site. Same thing.
