Windows 7: Microsoft Feeds Not Working

I have a Dell Studio XPS 9100 computer with Windows 7 Prof (SP1) and WLM
(Version 2011 (Build 15.4.3555.0308). The Microsoft feeds ( Microsoft at
Home, Microsoft Works, and Microsoft News) have been working without any
difficulty in the past. However, the computer has not received any feeds
for approximately the last three or four weeks. There has not been any
changes to the computer other than Windows updates, MS Security Essentials
updates, and MBAM updates.

Any suggestions in how to resolve this problem would be very much
appreciated, Sam.
