Wippen,
No problem. Here is the latest image of the layout (pretty much up to date), and the RR-Track file.
One difference is the observation platform construction in the aisles - they are or will be 10" high, and there are no steps; instead, I built ramps up and down from the platforms, and these seem to work fine.
Let me know if you can open the RR file.
Enjoy!
Alex
