Warhammer Forge in Armybuilder

[Elrowen]

I've got a bit of a problem as to I can't seem to add any Warhammer Forge models to my army lists in Army Builder.
I've chosen the options to be able to add forge world and warhammer forge models. But I can't seem to find them anywhere, nor find any solution to the problem either.

Do I need to download any additional data files or have I just messed up somehow?

Any help would be very appreciated!
