Ok this is exactly what you have to do. Start mohaa, then pulll down console and type in logfile 2 (just like that) and press enter, close console, attempt to play the level again, after it crashes browse to your mohaa/main folder and open qconsole.log with notepad. Toward the bottom of all the blah should be somthing to tell me what went wrong. Just post it here and I will get back to ya.
