You first need to download the progs source from the site, once you have it placed on a directory where you will work you can compile it using the VCC utility (which can be obtained from the site too), then just create a new VC file using notepad and add the code for the new monster you want to do, it's not diffcult, you can see how monsters work by looking into the progs source, once you get the idea it's a piece of cake, if you have anymore questions, keep posting in the forums.
