For some reason I can't seem to login. I've checked that my credentials work on the web login, but CuteSpotify simply rejects them without error. The Accept glow makes no difference. It has so far made two directories under /home/nemo/.local/share/CuteSpotify. One is CuteSpotify and contains a file called settings and a subdirectory Storage containing one file index.dat. This was created first.

The other was created during my login attempts, and is called CuteSpot?. It only contains index.dat.

Edit: CuteSpot\021 to be precise.
