Can't get Google Play Music to work

[mrsmumbles]

Well I bought a song from the play store the other day only to find that Google Play Music will no longer play any music on my Nexus 5. I do have PowerAmp set as my default player (I think) and I cleared the GPM app cache. It should work but it doesn't play anything at all, none of my other music either. Ideas? Thanks.

Fixed it by uninstalling updates and reinstalling.
