Received via email from a friend:

can you post my question?

Patch 10, fresh reinstall, still loops.

If I try to logon to forums, it says no character attached and I can't
post the q.

Hello Schwarzenegg

They may want to shoot an email off to beta.techsupport@us.battle.net because it is fairly difficult to troubleshoot an issue through a third party.

My first recommendation would be to right click on the executable for the game and chose run as administrator.
