    Windows 2000 5.00.2195 SP4
    Windows Media Player 9 version

    Everything's up to date and there are no new updates available for what I've

    I downloaded a DRM-protected WMA audio book from my library. I did the
    security upgrade thing and played the first minute or two of the first
    chapter. I'm pretty sure I backed up my license stuff. Then I ran out to do
    an errand.

    Now my audio book won't play. I get the heinous "Windows Media Player is not
    installed properly. Reinstall the Player." message when I try to do the
    "security upgrade" that it now asks for every time.

    I reinstalled the player to no avail. I tried to restore my restore my
    license, only to be greeted with the same odious error dialog box.

    I ran c:\winnt\inf\unregmp2.exe /updateversion in a command window to no

    So can I no longer listen to DRM-protected WMA audio books from my library?
    Is this what "protected" means--that you can't access it?

    Actually, that's really not a good sign. That should mean that your system
    cryptographic store is no longer valid and isn't accepting further
    additions. This typically would require an OS reinstall to fix. =\
