Ok, hmm first did you directly download the program from the main page? if so goto
http://krypt.dyndns.org:81/dcfactory/download.phtml theres a big message saying that something else needs to be installed first, so your best bet is to try that.
If that dont work post back your specs (ie. what os your using) and ill try and help some more, but try what it says on the site first.
