so i was writing in guitar pro a few minutes ago, and i exported the file to a midi so i could see how long it was, and it stopped playing back in the actual program. so when i try to hear what i just wrote, nothing happens. i've restarted my computer and all, anybody have any ideas on what happened? or could fix this?
A good way to fix this would be to get tuxguitar.

Other than that, I have no idea. Redownload Guitar Pro?
open your volume control, the sw synth bar will be tuned all the way down. this some random error that you get when you play midi files hen try to play a guitar pro file. its stupid, so everytime you play a midi file in media player or whatever, you have to go into the volume control and turn the SW synth back up.
