Update:
It seems like some update, be that a driver update or a Win10 update has stopped the game from working on my PC. Think I have done 2 major Win10 updates since last successfully launching the game, and probably a small handfull of video driver updates.
Currently, launching the game seems to get it started, it blacks out the screen, I see the in game cursor, then both my screens flash black (dual monitor system), then it drops back to Win10 desktop. I can see a resolution change has tried happening as well as the desktop icons are in a slightly different location, but fences seems to kick them back to their correct spot just about immediately.
