Well, mamewah was working the first couple times i launched it.. then i put in a path for a music file. So i am guessing at this point it created the mamewah.mus file? Anyway, my path was wrong or something...and i got that error. All I know is once i added that music path the error started. So, I went back into the ini file and removed the path completely, but it was still giving me the error. So i decided to look into the Files folder and i saw that file (mamewah.mus) and decided to delete it and try to launch the FE again. It worked. So for some reason, that mamewah.mus file was created and was causin it to crash, even though I changed my .ini file back. Who knows! Oh, and i originally placed my sound file in the root directory and had that as the path...i then created a Sounds folder and put it in there in case it was causing a problem.
the error: error 445 Object not found.
Sorry my attempt at describing this is so weak...im half asleep. 
Thanks...
The mamewah.mus file should normally be deleted when MW closes...the crash you encountered meant it didn't get deleted. Not sure exactly why that error occurred but I'll take a look into it...
