Running a N/W 6.0 SP5 system with iFolder 2.1.3

I havn't been into management of iFolder users since I upgraded to 2.x last summer. But today I went in and when I go to manage a user i get the message iFolder User is enabled but account has not been activated by the user. iFolder is working fine for me, but just can't get to manage me or the other two users.

Any clue as to what I did? I did install the N/W SP5 back in November. Did that break somthing?
