All Nick has to do is read what it says on the the front page of the site he consulted (see my link, which I also gave him last time he had a problem there). If he can't be bothered to do that, it's not surprising he thought that it was something to do with the official DT.

The page(s) indicated in the conversion links there don't exist, which is why invoking them results in a (customised) error message. Naturally I checked the contents of the relevant directory to be sure.
