I experienced the following problem with Dreammanager:
yesterday I made a new repaint of the DF Dakota and I installed it with Dreammanager but when I launched FS2004 I discovered that DM installed only the external textures. No internal ones.
The same happens with the DF Bonanza but not with DF Baron58 RXP.
I must say that, last time I used it it worked perfectly both with the Dakota and the Bonanza...
I can not figure out what is the cause, I tried re-installing everithing (DM, Dakota Pack and Bonanza Pack) without any result...
