Hello @GeografoNerd,
I´m sorry to hear that. I´ve checked your Dxdiag (thanks for that) but cannot spot anything out of the ordinary. Your setup is completely different from @Sour_Cheesil's one hence there isn´t a connection to be made. I think what would help is taking a look at the Msinfo of your systems. However, we can´t request them here on the Forums due to data protection purposes. I´d say the best course of action would be to contact our customer service directly and let them check it for you. If a solution can´t be found our Tier 1 Agents have the option to escalate cases like these to our Specialist Department who will be able to take a more in depth look.
To contact us please click here and make the appropriate selections. After that you will get the option to either start a chat or request a callback from us.
I on my side will get in contact with our QA Team and see if this is something they have seen happening before. I´d appreciate if you could update this thread once a solution has been found so we can help other players like yourselves better in the future. Thanks and sorry for the inconvenience.
