Heavy Hauling New Download

I purchased this scenario a few days ago, it says in the brief about it, that its part of a 'mini' series, for Ohio 2. I can load the first scenario, but non of the others work. I admit I'm not the best person when it comes to computers. But I downloaded all of the item that were required, that I didn't have, or have tried to. By 'tried' to I mean, I downloaded the files from the locations I was told to go to.
But two item, which seem are a 'must' have, do not seem to be recognised by the Railworks program. They are both reskins, and rewrite the Default settings. One is a reskin of the SD40-2, and yes I have this loco from RCS. The other is a cylindrical hopper, which, I can't seem to find, on the Golden Age of Rail site. Both files are zipped and I have extracted them.
This is the Read Me file for the cylindrical hoppers: (hs-cylindrical-hopper_cn re-skin package for Kuju RailWorks

NOTE: models are Freeware can be found at http://www.stephan-michael.de/railsim/index.html
To install extract to a temporary location and run packagesetup.exe.
NOTE: this will replace Default painted hoppers.
Have Fun!

Each has an Application file, and two other files. In both cases these files are labled Scenario qqg and Scenario yyy Type QQQ File and YYY File respectively.
Each also has a Railworks Folder, with a number of other Folders inside, but non of them have anything in them.
Any help would be grateful.
And although I can so far only use the first scenario, I would like to get it up and running, as it looks like the kind of thing I'm interested in. Big consists.
