It has started to work again. No reboots, no repair.
The only thing I did was try to attempt to play a .wma file obtained from
http://support.microsoft.com/kb/316992/en-us and it worked. Then all my
previously downloaded .wma files worked.
I will speculate that it might be related to DRM.
Since this is the second time that this has happened in the last few months
( I did not have any .wma files with DRM before), I will try this routine
again if the problem develops again.
I will report back if this 'solution' solves it the next time.
Thanks for the suggestions.
