Errors due to Digital Rights Management (DRM)  constraints in Windows Media Player (WMP) – be it in Vista, Windows XP/ 2000 / 9x / Me – can be quite annoying. This happens particularly if the media file is copyrighted and thus frequently shows DRM license errors. The only solution to this problem is to change the copyright (i.e. DRM) settings of Windows Media Player so that it does not show error messages.

Moreover, there is another problem that can crop up while using the FairUse4WM (FU4WM) – a handy application that removes the DRM component of the copyrighted media that you purchased – and you might get an error message saying:

<filename> does not appear to be licensed to you

This error arises primarily because Mirakagi tool gets started before the license is actually acquired by FU4WM. A simple suggestion is to wait till the Play button is activated before you press the Start button in Mirakagi. However, if you have not installed the copyrighted media’s license key properly, then this error will keep on cropping up and you will have no other option than to reset the DRM license settings manually.

Also, you should know that resetting the DRM settings in WMP is equivalent to re-individualizing WMP. This means that all the media DRM licenses will be cleared and the DRM settings will be reset to a clean original state – the idea being that all errors are undone in the process. In this case, if you want to play the media file again, you will have to go to the site you bought it from, and buy a new DRM license that is valid.

You should read this informative guide to WMP DRM settings if you want to know more about this issue.
