LMS now not working on Ubuntu 12.10

LMS has been working fine on my Ubuntu box but has recently stopped working (ie I can't access the browser GUI and access it from my Squeezebox Radio). I have tried uninstalling it and reinstalling but still nothing. The install process does not throw up andy errors. I have also tried running the restart command in the terminal. Still nothing.

Can anyone tell me what is wrong? I am pulling my hair out!

I am also running Plex Media Server on the machine - could this conflict with LMS?

I can provide a log file if someone can tell me where it is located in Ubuntu!
