Did you ever figure this out? I am having the same issue..type in server name, see authenticated message but filter box is empty and if I try to type some path in I see an error in the log console that says No Nodes! Cannot render list.
Authenticating user completed. Authenticated = True
Opening document completed.
Getting objects completed.
No nodes! Cannot render list.
Yes I am logging in with admin account. I am being properly authenticated. And the tool is located on the QV server. I saw an earlier post that this was a confirmed bug and was wondering if it has been fixed. I see that it is also possible to use the management console to change users on objects, but with no way to filter, this would prove to be a very tedious task.
