Ive been working day in day out on my game. It previewed fine, exported fine. I wanted to clean my computer up a bit, so i backed my game up and reinstalled windows. Now NWJS is broken. Its happened before and i went back to an older version of NWJS..but this time the problem persists..! All i did was reinstall windows. Previous versions of my game now dont run. I get a back screen on export, or if it does run i get a strange reddish overlay, or a flickering screen with music. Pretty disheartened at this stage..why make a game when you cant run it???!!!
