Amazon Instant Video Silverlight Content Protection Error

On my main Windows 7 Ultimate Desktop I have the latest NVIDIA drivers and the latest version of Silverlight and whenever I try to watch a Stream from Amazon I get error 6036 "Your system does not meet content protection requirements".

It quite clearly does, since I have an MSI N470GTX and a Samsung S23A70D monitor running on Dual Link DVI at 120Hz. Both obviously support HDCP and I've deleted the "mspr.hds" file that is USUALLY located in "C:\ProgramData\Microsoft\PlayReady", however because my C drive is an SSD I put my entire User Profiles on E, so in my case it's "E:\ProgramData\Microsoft\PlayReady".

There are a number of methods for fixing this according to the internet although none that I've tried has worked as yet. People said that the file can often get corrupted when upgrading from an older version of Silverlight so people have deleted it and redownloaded it and got their Netflix Stream back again, in my case it got created when I first tried to stream a video, I've tried uninstalling and reinstalling Silverlight with no luck, and I've tried plugging in my HDTV on HDMI.

None of these have worked, and the only thing that I've not tried is installing an older version of Silverlight, and plugging in my monitor with HDMI instead of DVI on the off chance that is the problem. Ironically my Dad can play the streams on a Vista machine with an AMD Quad core CPU and on board Graphics, however the monitor on that computer uses VGA as against DVI or HDMI which is why I think it works ok.

Anybody got any ideas besides trying to find an outdated version of Silverlight or trying it in Virtual XP?

Tried disabling Hardware Acceleration in both IE and Silverlight with no joy. According to this Sky forum that details some Silverlight Errors (Silverlight Error Message List. - Sky Community) error 6036 is "Graphics device's driver certificate is invalid". This clearly can't be the case since I've updated the graphics drivers recently and NVIDIA always have signed drivers. Unless I need to uninstall the graphics drivers then reinstall the latest version on the off chance something is corrupted?

Interestingly I cannot watch any License enabled video or listen to any license enabled audio from Microsoft PlayReady Test Server - Silverlight and Expression Encoder, it just stays on "Acquiring License" no matter how long I leave it. This is frustrating me because currently the only way I can watch videos is to use my PS3 on my TV, which I can't do as and when I want since my parents want to watch TV programs on it most of the time.

I've cleared IE Cache and all PlayReady cache (including the Protected Operating System folder named "Cache" and Silverlight downloads all the same files again but still nothing works. I have updated the graphics drivers since I first had this issue but this had no effect unfortunately.

Did you get any joy with this? I am having the same problems trying to use SKY Go.

I get the 6036 error - I have also tried the Silverlight DRM test which will not play protected content.

My system uses Win 7 64-bit prof; AMD7970 graphics card with 3 monitors connected. I have the latest AMD drivers and have reinstalled Silverlight (several times). I tried an old version but the Sky site just insists the new version is re-installed; I deleted DRM folder content and play ready folder. I also tried IE11, Mozilla Firefox and Google Chrome browsers.

I also have my programme data on the D drive.
