Hi Michael,
I have a similar issue. Was on v7 (worked ok), just bought v11, my system is HDCP, HTPC connected to receiver with HDMI, receiver to Optoma projecter. Getting error 0121. When I run nvidia diagnostics, HDCP is enabled, but BD advisor tells me it's not.
I went to the link you suggested, and land on the "welcome to posting on v11" generic link, no specific info on how to fix or options. (I am missing the right link - apologies if I do, please direct me where I should go)
What next steps would you suggest:
- try to fix (you seem to indicate the feature has been sunset, any path for a workaround?)
- go to v10 (if I can get it)
- return v11 for refund
Thanks ahead for any help you can provide
Cheers
Stephan
