first thing you need to do is check wherever you installed dominions for a "mods" folder. if its there, all you need to do is unzip the .dm file to the mods folder and the .tga(or whatever it is) into the maps folder.(if its not there, just create a new folder named mods and do the same thing)

go into dominions, select preferences --> Mods, then enable the 5.2CB, and your set!
