Well repeat after me: "Grouping is my friend" Do a search on posts by me about grouping. And how do you expect it to write to disk if it does not open a file first? It opens two of them I think one for the finished render and a temp file. Try this do it again and render to disk with a new file name and give it time, lots of time. It never says finished rendering does it? Wait for it to say that. It could take days depending on your system and scene. You may want to see my tutorial on tile rendering.
