SYMPTOMS
When you try to play back content that is protected by Microsoft Windows Media Digital Rights Management (DRM), you may receive one of the following error messages:
Message 1Windows Media Player cannot synchronize or burn the protected file because the Player cannot verify that the license is valid. A problem occured while contacting the Internet to determine the current date and time
Note In this message, "occured" is a misspelling of the word "occurred."
Message 2A problem occurred during the security upgrade. Try again later.
Message 3An error occurred during license backup or restore. A required Web page cannot be displayed.
Message 4To play the file, Windows Media Player must download a license from the Internet. However, the license server is not available (for example, the server is busy or not online).
You may also experience this problem when you try to do one of the following tasks:
- Synchronize content to a portable device
- Download security updates
- Back up or restore licenses
Note The process of upgrading the security of the DRM components is known as
individualization.
CAUSE
The Microsoft Windows Media Player 10 contains a malformed version string. This version string is added to the HTTP header when the Windows Media Digital Rights Management subsystem makes HTTP requests such as the following to the Microsoft forwarding service:
- Backup and restore
- Individualization
- Synchronization of the secure clock
These requests are sent to the Microsoft forwarding service. However, because the HTTP header contains the malformed version string, an HTTP error causes the forwarding service to fail.
RESOLUTION
To resolve this problem, uninstall the software update that is discussed in the following Microsoft Knowledge Base (KB) article:
