Just in case, I have screenshots of my file in the links:
Arrangement view:

Session view:

The problem is that after selecting the option to export the music as WAV, it loads like it should(the loading pop-up with the yellow status bar), but when I try to play the WAV file, I get nothing. The clip lasts less than a second, and it has no sound.
Export settings:

How can I correct this? Thanks in advance.
