Hi guys, I figured out what the problem was. As I said before I had doom3 installed to the folder "/home/TpnySmith/Games/Doom3". Also the darkmod files were located in the folder "/home/TpnySmith/Games/Doom3/darkmod". I moved all files to the folder "/home/TpnySmith/.doom3" and then it worked fine. I never thought of doing this as Doom 3 works fine when installed to any folder in my home directory. It does not have to be in the ".doom3" folder. This usually only contains the configuration files and the cdkey. Anyway, thanks for the replies guys. I appreciate the help.
