Missing (custom) shaders in Quake 3

[Dirge Inferno]

Hi, I've got a weird glitch in Quake 3 where the custom shaders I've made don't show. They use to work perfectly until today, I haven't even touched any of the files since last night and now it says in Quake 3 that the textures are missing, but when I look they are they're and the shaders have no errors in them. I keep getting "WARNING: Couldn't find image for shader" in the console for the shaders. The default shaders work perfectly fine though. Could Q3Map2 be mis-compiling the shaders as textures? Because when I create an image file named with the shaders I have problems with and compile the maps that's using them, I open then level and it shows the textures.

I do have it at 0, and all of this was working fine last night but now it just stopped working out of no where.
