Security component upgrade
This page lets you upgrade the security components of your digital media player so you can play protected files on your computer.
To upgrade your security components, click Upgrade.
Note: When you click Upgrade, your computer will connect to a Microsoft-operated Internet site and send information about your digital media player, including a unique hardware identifier. No information will be sent that can be used to personally identify you or track your activities. Microsoft will then upgrade the security components of your digital media player to ensure that it runs with optimal security.
At this point the "UPGRADE" box was "grayed-out" and non-selectable.
Bottom line: not allowed to upgrade component security per instructions and was not able to advance in the sequence to play the DVD.
Any help or clues appreciated.
