Oceansize

does it show in your control panel? or you can go view-toolbars-customize..-and add folder options

Tools in windows explorer, not messenger.

Click on the show details thing, whats the error code? Google it and you could probably find whats wrong. Something similar to what you described happened to me a few days ago, the error code was "8e5e0158". Source:http://windowslivehelp.com/community/t/28846.aspx Give that a try.
