As i said worked just fine yesterday, but now i just get "Cannot find message file" when i try to start the game.

Re-install Java. If that doesn't work, go into your system variables and create a new variable called JAVA_HOME and put your Java path in it.

That's quite weird because nowhere do I give "Cannot find message file". I can only guess that it's Java erroring out or something like that, so I agree with trying to reinstall Java.
