CD Airfield Buildings Library 4.0

I am installing the files, if I don't put in all the files in the OBJECTS_DP folder, it works.

I will get this error "generation of quick combat mission failed!" when I put in all the dp files.
I am now putting in a few at a time, it started to get this error when I put in these two files:

09/16/2019 04:29 PM 2,877 CD_Hangar_B1.dp
09/16/2019 04:29 PM 2,877 CD_Hangar_B1_Green.dp

They look OK to me.

I hope that someone know what I did wrong.
