Are you able to run Alma Valley, John? I can run the default session if I don't try to take a screenshot. The instant I try a screenshot I get a CTD. And I can't create my own session, as once I assemble a consist of any kind and then try to drive it, the instant I hit go I get a CTD. Beautiful route, and I had to replace on payware bridge and one payware tree, so maybe my subs are causing it...
