When I try to generate a sleep nap, pzizz crashes. What's going on?

Older versions of the software required that the Energizer and Sleep modules be downloaded individually. Please download the latest version and reinstall the software.

When I try to export a soundtrack I get "The exporting of your nap(s) has failed due to error..."

This is most likely due to the fact that you have a Smart Playlist and a "regular" playlist both called pzizz. Deleting one of these playlists should solve the problem.
