So I have been trying to use a Gears of War GPD editor. I am running into a problem where I extract my 4D5307D5.GPD file from my profile on Horizon and attempt to load it on the GPD editor. The issue is, every time I do this, it just tells me "Can not open GPD file" After a few hours of researching, I am unable to discover what is causing this to happen. So now I reach out to anybody else in hopes of somebody knowing how to fix this issue. Any help would be much appreciated.
