Back when I helped demo the Lords of War game I uploaded all of the audiobooks into Boardgamegeek so if you look under Orcs versus Dwarves video section they should be there. Regarding the website it has been down for a long time now and the company has closed so I don't think you will be able to get this information anymore.
Any chance we might find out someday what happened? The only thing I've heard was some legal issues and/or gag order? It's a shame, LoW is a fun game and was gaining some great momentum with each KS... plus I have this huge box to hold it all and there is soooo much empty space.
EDIT: More digging turned this up.. bummer.
