"Skip" problem

[Lloyd Te Kani]

Lately I've suffered a number of problems which you have been able to resolve for me. The latest is as follows.

Halfway through a gig last night and suddenly every song I search and enter into the playlist comes up with the "skip" option beside it. I rebooted a couple of times but to no avail. I completed the gig with a back-up laptop and re-booted my system again this morning but the problem remains. Obviously any help provided would be appreciated
