DP-02 problem importing wave file...

[cjl120120]

Hello, I've been trying to import a wav file to a completely new, blank song on the DP-02. I feel like I've done everything right; I connected my laptop to the unit, sent the file over to the DP-02's WAVE folder (its a 31 MB wav file), and disconnected the unit safely. When I go to import the track on the mixer, it says "Import file not found." The track is definitely in the folder, as when I reconnect the unit and open the WAVE folder, the track is there. Yet I can't seem to import it for the life of me. Any ideas??
Thank you!

hi, i had the same problem when first got my dp02. as usual with these things the answer is simple when you know how. check the format of your WAV file. it has to be mono.
