6.7.1 Continuous Playback Issue
The USB export debacle has been rectified with this latest update, but continuous playback is still an issue. As with 6.7.0, when in continuous playback mode, it says "Load Error. File cannot be found" for the next track. But the next track is physically there. I can manually load it & there is no exclamation mark.
