I copied a bunch of CD's onto my computer (laptop) a while ago and have
enjoyed listening to them for sometime.  I recently acepted a windows update
to update the player and ever since then I am unable to listen to my copied
CD's.  I get directed to a web page as below which asks me to download a
licence.  However whenever I do I get an error that says "Error 438; unknown
error occured when storing your licence".   I have no idea where these
licences are stored however another user had a similar query and the
suggestion was to delete the files in the DRM folder located in C:\Documents
and Settings\All Users\DRM however when I look in this drive there is no DRM
folder and when I try to create one it says I cannot as one already exists
(not that I can see it)
