The sessions in question are the last 3 maps and and sessions put on the DLS. Don't know how to contact Gary Evans, author of these layouts and sessions, but thought he should be made aware that their are some problems with his latest works. I don't think that the problems I am experiencing are with my computer, as all of his other work before this point works great for me, In the most recent work, just released on December 2nd the yard that he starts in has very little trackage and the train(not visible) that he uses does not appear at all. All that is seen is the smoke from the exhaust of the train traveling along(no tracks) as the scenario progresses no train visible, no train cars and almost no track. As far as his next to the last work is concerned the tracks are all there and the Starting engine is visible and at the very first part there is his audio but then the scenario stops progressing. Not complaining because I like all of his other work. Just wondering is anybody else experiencing this problem. Like I said I really don't believe it is my computer because all his other work runs fine on my machine.
