DJ2.2.0 No access to external disk tracks

The issue as described in http://forum.mixvibes.com/viewtopic.php?f=403&t=25995#p162924 happened again after installing the release 2.2.0.
Tracks stored on a non-local drive are not found. With Explorer I could browse to the tracks (win8).
Local tracks were found immediately.
This time I just quit and restarted 2.2. This resolved it.
Yesterday the drive was a mapped network drive. This time it (same hdd) was USB connected with a Subst mapping to the music folder.
