Provide me with a list of addons you have installed. There may be something that is preventing gmDoom from generating the textures.

I don't think I can do that. I have a ton to list.
*Edit: http://imgur.com/a/aUr4g#0 <- That's my addons

I've just added the concommands "gmDoom_info" and "gmDoom_spewaddons". Run both commands and post the results of each.
