First thing to try is to add the textures2 folder to the resources.cfg file if you haven't already.
Next if that doesn't solve anything, could you open the .map file in notepad and Ctrl-F search for "SkyBoxTexture" (without quotes)? Can you find anything?
If none of this works, try to make a very simple map. Just a plane, PlayerStart area and a skybox, open it in the game and make sure it doesn't work, then upload it somewhere (just the .map file should be enough) and send me a link by pm and I'll have a look.
