Trying to create my own song can't pull up an accent wave file?

Brand new to the beatbuddy. Just wondering why I can only pull up midi files but not wave files. I created a new song and start filling in the blocks but when I got to the accent for the footswitch the files were blank and there were no wav. files.

You should use MIDI files for all song parts except Accent Hits.
You should use only WAV files only for Accent Hits.

Daef, Im having the same problem, everything seems to be working now but, when I want to add or change an accent hit I click on … and my default_Lib is empty. My user_lib Is also empty. Thanks!

I deleted the BBWorkspace and re-downloaded it and that seems to have solved that problem.
