Downloaded, but not streamable tracks won't play

Never mind, solved it IT Crowd style by simply switching the download toggle off and on again.

My Question or Issue:

I added some files that are not available for streaming to a downloaded playlist (Dismember - Dreaming in Red and Masters of Reality - The Blue Garden). I own the cds and I have ripped them to mp3s, so that should work. Indeed the tracks do show up in the playlist in white with the green arrow next to them. But they won't play. When I click on them nothing happens and when I put the playlist on shuffle they are skipped. I tried logging in and out, but that doesn't help.
