The product advertises a web site, and the link appears to point to a "parked" domain with no content. Sure, it's a free download, but it's pretty much an advertisement for the Dungeon Dwellers Guild, which doesn't appear to be at the specified web address.

Went to the game site a couple of times to use it, but it is not something I can use offline. It's a nice web product, though. I'll probably go to it every once in a while to use the random tables when making up an adventure or campaign.
