HELP Power Cut

[Aidan]

Hi
I was gigging with my Hoster the other night, and the venue had two power cuts, which of course shut my computer down as well as my hard-drive, so when it came back on I carried on at the gig even though every time i'd search for a song in Hoster (while someone was singing) the music would stop for seconds then it would go again, any ideas what I can do to sort this.

Just to clarify when I search for a song the Audio stops, when I stop searching for a song, the Audio starts.
