Devialet Air 2.1.3 Driver stopped working

[agentsmith]

Out of the blue my Devialet 2.1.3 for Mac driver refuses to load.  With the following error message when trying to load the following message popped up:

Devialet Air 2.1.3 - Error
The Air Virtual Soundcard could not be loaded
Plese restart your computer

Restarting the computer did not help.

The strange thing is I do not recall making any changes on my system.

System details:

Mac Mini Mid 2011
2.3 GHz Intel Core i5
16 GB RAM
Headless mode, access by Screen Sharing
 
OSX 10.8

I tried a few things including uninstalling, re-download and reinstall, removing several unused software.

Any clue on how to debug this?

Thanks for any offers to help
