Opens to a Loop

Suggested

I was working on editing a group and when it went to update it just froze with the hour glass but nothing happening (and I waiting and nothing).  I used Task Manager to get out of the system since I could not log out.  Now everytime I go in it is in that same screen and does not do anything, I have even restarted to see if that would break the loop but nothing.  What can I do?
