sky drive tells me that it cannot access NoteBooks

My password works to log me in to Sky Drive, Windows Live and Windows Office 365.  I have several notebooks in Sky Drive.  I if I click on “recent docs” I can see these notebooks but if I try to open them in either NoteBook desktop version or NoteBook Web App I get the following message:

“This item might not exist or is no longer available

This item might have been deleted, expired, or you might not have permission to view it. Contact the owner of this item for more information. “

The items do exist.  They have never been deleted and I am the owner. I both created them and am the only person to access them. Things I can access identify the location simply as “sky drive”. Those I can’t access give [MY NAME’s] Sky Drive” as the location. 

Yesterday while trying to access docs and notebooks I got a message asking me to sign in again to verify my identity.  The log in recognizes my windows ID.  But when I input my password, the same one that opened SkyDrive, Windows Live and Office 365, I get a message telling me the password is incorrect. Today when attempting to open a Word doc created yesterday, I get a message saying there are problems with the server and I should try again later.
