Triode spotify pluggin don't log in Spotify

Sorry if this has been already responded but I couldn't fine any help so far...

I am running squeeze server Version: 7.5.3 - r31792

I have been using Triode spotify pluggin for months with no problem with a Spotify premium friend account.
Now I decided to create my own Spotify account, then upgraded to Premium.

I changed the credentials in the pluggin settings and it doesn't connect anymore to Spotify.
When I run the test in the plugin setting page, the test stops in the 4th test.

Helper App: Running
Not logged in to Spotify
Login Error: Password not set
Last Error: No error

I removed the pluggin and reinstalled it.
I cleared the preference in the Squeeze server control panel.
I restarted the server
The firewall is not running
Nothing changed.

The Helper log shows repeatedly :
