Anti-Splog Api Key is not working

Hello guys and Happy New Year !

Today I wanted to activate API key for Anti-Splog plugin and after completed the field with API you provided ( as premium user ), I pressed " Check key " and I received this error several times :

Anti-Splog is not fully enabled. You must enter your WPMU DEV Premium API key to enable the powerful blog and signup checking. More info» Dismiss

There was a problem connecting to the API server. Please try again later.

What seems to be the problem ?
