Hi -
I'm getting the same problem, it just started a few weeks ago. Seems like Steam did an upgrade and now I'm having this issue. I have the latest Nvidia drivers.
I play for a few minutes and then the screen goes black. The "HDCP error message" displays.
I was able to reboot and get going again for a few minutes but it recurred.
Any help will be appreciated.
