1.8.2 upgrade from 1.8.1

I upgraded today to the 1.8.2 version of airtime using the ppa.

The upgrade was fine but unfortunately there is no sound. Icecast status displays airtime-offline.

The system check passed, but when I typed 'airtime-update-db-settings' the final output was

propel > sql-template:

BUILD FINISHED

Is there something I can do or should I just reinstall 1.8.2 from scratch?
