Flac files in Quicklook with Fluke

[Jolly Jimmy]

I've had Fluke installed for a while for playing .flac files with Quicklook and in iTunes, but now Quicklook suddenly no longer works for previewing flacs. I've reinstalled Fluke a couple of times and uninstalled every other app that deals with .flac files but it still doesn't work. Any ideas as to what has made it stop working all of a sudden?

Thanks.
