Nothing's changed on my systems.  All I've done is taken my laptop to work and back like I have several times this week.

I get home and magically my desktop's MP icon remains black despite rebooting and reloading MP on both machines.  Run thru the wizards again, no luck. Reconfigure both manually, no luck.  Reset router, no luck.

Set MP up as primaries on both machines and BAM it works again.  This is the 2nd time this has happened to me where setting both machines up as primaries has been the only solution.

I wonder how long til it breaks on me again. 

There is a serious lack of unhappy emoticons available for me.  I'm mad about that, too.
