[SM-USERS] ERROR : Could not complete request. Reason Given: SUBSCRIBE failed: Can't append to subscription database

Hi Squirrel lovers! 

ERROR: Could not complete request. Reason Given: SUBSCRIBE failed: Can't
append to subscription database

Has anyone seen this error before? I have been able to get mail portion
working, but it will not display the folder list on the left hand side.
If anyone could shed some light on this or point me in the area of
trouble shooting documents; my brain cells will be happy for the help. 

Thanks! Kevin
