Very strange, WMP11 has been working for me since I installed Vista some
months ago (Vista Ultimate)....but now when I open I get the message "There
are no items in this library yet - the player is searching for digital media
files in the background" yet it never finds any. I also go to Library > Add
to Library and click "My Personal folders" I then also click Add and
manually add the folders I have music and photos in and then click OK.

Nothing happens, nothing is added. The files are there but nothing. Any
help ? I dug around Control Panel add/ remove programs trying to find if I
could re-install WMP11 but there doesn't seem to be an option.
