An institution's subscription to Factiva consists of a finite number of allowable sessions or concurrent logins.  What this means is that a predetermined number of active sessions are allowed based upon your institution's direction.  Once the number of active sessions are reached, any subsequent attempt to access will be met with the message appearing just above.

Solution:  Wait until a new session becomes available (this happens when another user logs out) or you can check with your Account Administrator to verify you are accessing the database correctly.
