After reading the Deezer posts, I was keen to give it a spin.
In order to install the app, I must log into mysqueezebox.com, this is where the trouble begins.
Somehow, when I first installed LMS, a .telkomsa.com email account was used to register the SB3. Later I used my current email address to log into mySB.com.
It would appear that in order for Deezer to install, the login details for mySB and the player must be the same.
As the .telkomsa.net account no longer exists - I don't have the password anyway, there is no way I can think of to unregister the player from that account.
The last resort is to contact Logitech, but how? Has anybody done this?
