PlayReady has started to fail for some reason

I'm trying to run the PlayReady sample ( on my machine but am continuously seeing the Playback Failed screen.

This was working perfectly fine for me a couple of days ago, and I can't figure out what might have changed to cause the error. Is there something I can do to identify what's going on with the certificates?

I'm getting the following logging output:

Enter Playback.Play()
Creating protection system mappings...
Creating media extension manager...
Leave Playback.Play()
Enter Playback.ProtectionManager_ComponentLoadFailed()

Most likely you have upgraded your graphics driver to one that has not been signed for DRM protected playback.
