I've been composition a song, and now I'm trying to save my .MUS file as a .MID file. Its worked every single time until today, and now it keeps getting an error and closing on me. Its VERY annoying. Anyone here know how to fix it? It would be really nice to convert my composition.

Never happened to me...try re-installing Finale.

That's never happened to me before.. maybe if you restart your computer or as Noir said, reinstalling Finale, it might work... Have you done anything to your computer lately that might have affected it? :mellow:
