nessus registration question

I am running: nessusd (Nessus) 2.2.2 for Linux

Is there any known reason why, after obtaining a registration key 
and - apparently - successfully running 

./nessus-fetch --register < key >

and restarting nessusd I should still be seeing:  

  
    You are running a version of Nessus which is not configured to receive
    a full plugin feed. As a result, the security audit of the remote host
     produced
    incomplete results.
    
    To obtain a complete plugin feed, you need to register your Nessus scanner
    at http://www.nessus.org/register/ then run nessus-update-plugins to get
    the full list of Nessus plugins.


in my nessus reports?
