You may have run into some problems getting the JBK C-54 (DC-4) working in CFS2.   

If so this will help you get her running properly by correcting some items overlooked in the download and install instructions. (Dave put together a complex package, so we'll let him slide....this time only.)  :

- There is no Model.CFG file in the player version Model folder, so copy and paste that file from the AI version's Model folder.

- A number of textures are missing from the player version's Texture folder, so copy and paste all the textures from the AI version's Texture folder into the Texture folder of the player version....just let them overwrite the existing files.

- The AIR file in the player version folder is the one meant for the AI version, so cut and paste it to the AI version folder.  Then rename the DC-4plyer.air in the player folder to DC-4.air.

This should get your player and AI versions running properly.....at least it worked for me.
