Have just upgraded SEPM from 11.0.6300.803 to 11.0.7000.975. Upgrade went smoothly and SEPM started, but now when i press on a column name to sort users in a group, it shows a dialog with title "Error", red sugn in the dialog without any error message and Ok button. After this it throws this error if i press a group, a user, etc. So i literally doing 2x clicks now to manage users.
