Just a quick one, whenever you edit the xdp file or the air.file you need to delete the file with the extension .bdp. the game will build a new one the next time it starts.
The BDP file is like a shorthand version of the compiled information contained in the xdp, air file and .cfg files, this helps the game run a bit faster.
If you do not delete this file the game will continue to run with the old information. If you have deleted the .bdp file and your still having trouble, I'll try to get it going tonight for you.
