I had this problem as well. I think it is probably a bug triggered by selecting one of the instruments. I was able to fix it by doing the following:
1. I exported the MIDI
2. Created a new sequence and imported the MIDI I just exported
3. When importing the MIDI, I made sure to not include tracks that had 0 notes associated
4. Saved the new file
5. Was able to export WAV and MP3
