I had the same problem. I turned on extended logging and found that there was a problem with the authentication service "Failed to handle tweener challenge". This occured when i used a live acocunt as opposed to a hotmail account. then tried to switch back. I found that by logging onto hotmail.com through a web browser resolved the problem. However did not find anything on micorsft's support site. Perhaps they need ot update a Dll to handle both passport and hotmail accounts.
