Hi Tim, it just doesn't get any better. I changed over to my w10 computer in the basement and started over with it. It's on the opposite corner of the basement and twice as far from the router, but it still works on anything else.
So I got it all set up, downloaded the 567ULT file on that HC sim, verified that it was in the right spot, and tried to load the file into an engine. I got a "No Program File" error. Tried another engine, same outcome.
It's gotten to the point where I would rather have another heart bypass operation than keep running into the same brick wall over and over.
Thoroughly disgusted Joe.
