Netflix vs. Silverlight: Error N8156-6013

Having installed all updates provided to me by Microsoft, at some point I installed the update to Silverlight. Apparently, this creates some sort of issue with the Netflix player and I received an error code (Netflix Error Code n8156-6013) informing me that the date (which was correct!) might not be. Netflix will tell you it's an error on Microsoft and Microsoft will say it's a Netflix problem.

The fix after much research is to delete a Playready config file mspr.hds (leftover from the previous Silverlight version) and allow the Netflix player to re-create the file using the new Silverlight installation.

The file to delete or rename (probably safer; in case something goes wrong just rename it back correctly)

On Windows XP:

C:\Documents and Settings\All Users\Application Data\Microsoft\PlayReady\mspr.hds

or

C:\ProgramData\Microsoft\PlayReady\mspr.hds

On Windows 7:

C:\Users\All Users\Application Data\Microsoft\PlayReady\mspr.hds
or

C:\ProgramData\Microsoft\PlayReady (Thanks Jarin)

On MAC:

HD > Library > Application Support > Microsoft > PlayReady > mspr.hds

Some fixes out there will tell you that this will not work and the only way to fix the Netflix error is to rollback Silverlight to the older version. WRONG! The important thing to remember is that you have to reload the Netflix player through your browser via the Netflix website. Enjoy!
