If this does not work, then I don't have anything further to suggest:
You shouldn't need any chains for the scaffolding, just the nuts and bolts. If you click on the top part to zoom in on the scaffolding, just hook the green links together, the red links together, then place the bolts to connect the two scaffolding pieces together.
It sounds like it might be kind of finicky in terms of hotspots or whatever.
