For the past 2 days, Windows Live Mail 2012 has been completely messed up.
1.  When I click on the sign in button, it brings up a window that has links to the privacy notice and terms of use, but NO LOG IN fields.
2.  I can see my inbox, but can not access my sub folders. When I click on some of the sub folders, the messages in other sub folders are displayed!
3.  Unread message counts not displaying.
4.  The small arrows to the left of the individual accounts in the left panel no longer display. Accounts that were previously open are now stuck open, and I can't open the others.

I have tried uninstalling and reninstalling, but the problem persists. Short of switching to a different email client, any suggestions? I really like Windows Live Mail. Switched to Thunderbird once, but switched back after a day because I like this so much better.
