Ok. I turned off windows update and followed the instructions exactly, but still no luck. Everything goes fine until I try and play one of my protected wma files, and then WMP 10 says something along the lines of "a security upgrade is required to play this file". After I click on "Yes" to upgrade, I noticed that it upgraded my IBX back to 11.0.6000.6324.

On top of that, when I try and open the file in Zune now, it gives me an error that says, "need to check usage rights..." I'm guessing this is because I haven't downloaded some windows update or something.

Has anyone out there actually had this downgrade to WMP 10 method work?

Edit***Well I figured out that the problem in Zune was because I was using the same audio file on all these tests, and you're only aloud to do so much with each file before they are locked. I called up Zune customer service and they unlocked the file for me.
