Sugarcube plays only Random Tracks / Can't connect to MusicIP / connect: timeout

Hi. Sorry if this s already answered, if it is, please point me in the right direction!

Sugarcube will only play random tracks.
Sugarcube and LMS are talking to each other - in the the web browser interface
Is it a Linux / Windows thing - the paths in the log look odd - but I'm only guessing...

Any help would be really welcome! :)
