Hello guys, sorry to see you are having problems.
I opened up the classfile for this and there does not seem to be anything special it asks for except it points to the C-47 cockpit, so I think you will definately need some kind of mod installed that has that active as there is no cockpit folder in the mod.
Other than that please check your entries are correct as they can usually cause a CTD.
I cannot suggest anything else as I did not make the mod and I can no longer find just where it came from.
I have it working in DBW 1.71 and Modact 4.12.2, my 4.11 with ModAct is knackered and will not start so cannot say for that other than it was at some stage because I have it installed and it has not been deactivated.
Wishing you all the very best, Pete.
