Can you be more specific? Does it not download, or extract, or run?
Oh, sorry. It does not open the link, directly. 404 error. Dammit.
Aw crap, it “only” stores the most recent 30, and there have been 30 builds since then, didn’t realize it was doing that. Ok, we need to specifically stash the haloween builds somewhere so people can get at them 
I still have one from 11/1 (if you need it): http://www.mediafire.com/download/ucwbpkdzqgk9mi4/cataclysmdda-0.8.zip
