I found that Pike & Musket likes to run exclusively on a graphics 800 x 600. You have to change everything to 800 x 600, including your desktop (there maybe a way around this, but it will be a while before I find it). Anyway, I've been playing through P&M 1.5 for quite a few turns. I feel optimistic. I'm going to make a copy of my P&M 1.5 file and apply the patch. If it works after that I may be on to something.
