I'm using Office 2010 and trying to Share a Notebook or Spreadsheet on Skydrive.    When i click the share button I get a windows type login prompt "Enter your Windows Live ID credentials", on the top of that it says:"Connecting to docs.live.net".   I type my Hotmail account information-
In the background it tries contacting the server, and in a few moments  it comes back with the same login prompt.  There is no error message or any other indication of any sort that the login failed-I can keep trying and trying and trying.  I have tried from another PC and it works.

1. The login is correct-I use it daily- I can login into my Hotmail and Outlook accounts without problem
2. I have tried clearing the password cache as mentioned in other older posts.
3. I can manually copy files to my skydrive account, i just can't use Office to do it. 
4. I have an outlook account as well. same problem.

It is driving me mad, can i get some help?
