[SOLVED] MB2 error launch

[Superman33]

I have the new Knights of the Force 2.1 installed as well as Movie battles 2. When I go to join a server on Movie Battles 2 it loads the "Awaiting gamestate" page but then crashes before it ever gets to the actual loading page. I want to be able to play both Knights of the Force 2.1 and Movie Battles 2

crashes before it ever gets to the actual loading page.

How exactly it does crash?
If there are any error messages, it's worst idea ever to not quote them fully and entirely.
If there are no error messages, you are supposed to mention it explicitly.

You can, while all KotF files are in its own subdirectory.
Remove all third-party (including KotF) .pk3 files from "Jedi Academy\GameData\base" folder.
