My biggest wish in skinning is to learn how to edit multiplayer maps. I've tryed to start up from here:
http://www.renegadeskins.net/t1496-adding-tiberium-mist-etc-with-leveledit (thank's to LeeumDee)
But I got a problem (as usual):
I've installed all what it was said there - Renegade Public Tools, a patch for it, XCC Mixer (almost have it), and also got the Multiplayer Level Files Pack.
The problem is when I'm starting up the LevelEdit (patched) and choosing the Mod Package, It shows me the small square Start Up screen and in 1-2 seconds after that it just crashes without any word.
Please someone tell me what did I do wrong and what I gotta do now?

i whould like to help you bro but i dont know a shit about leveledit, as for edit maps do you mean to change shapes or objects that is renx´s work, i believe that if you change more than textures in map it will became unable to play online whit it unless the server has the same files but i am not sure about this, perhaps you should post for advise in reneforums i am sure some ppl there can help you whit this.
