I can't see Vilverin in the Construction Set. When I try to enter any of the cells, I get an empty screen. Items are listed, I don't see anything though. Is there any reason for this?

Do you know how to use the CS?
What did you do?(Step-by-Step please)

Did you try double clicking on the cell in the list? Or on any of the items in the item list that shows up when you click on Vilverin?

Sometimes, when an interior cell is loaded, the 'perspective' is so far away that the items in the cell are not rendered. Do as Povuholo suggested and double click on one of the listed items.

Simple... I double clicked the cell in the Cell View list. I did this on my PC upstairs, Vilverin still did not load. All other cells load in the render window, however.

I assume all you're getting is a grey screen, in which case you might want to try reading your responses ^

In Cell view (where you choose your interior) Go to the right hand list which lists all the items in the cell. Then double click on an object (I know double clicking on "ARDoor01" works for sure cus I just tried it).

This'll bring you to that object which in turn will render the rest of the stuff.

If this doesn't work then check in game to make sure vilverin is loading in game
