Ashley That must be it, i thought it might be more a problem of 3rd Party Addons but my main project has the physics behaviour in it. Any chances this will get fixed or is "fixable"?
EDIT: One of the things that seem to go different with my project is, that instead of crashing or an error report or anything it just shows a black screen... I wanted to ask in general, since i'm at a stage with my game where i no longer feel comfortable to share the .c3p file publicly if i may send it to you via E-Mail in case you would like to take a look?
