Under Graphics, hit the Reset button. Then adjust the Gamma and Resolution sliders up. This should fix the dark/blurry problem. Happy Smithing!
when I click reset nothing happens it just minimizes the game and when I open it again and go to adjust the gamma slider there's like an invisible barrier keeping from moving my mouse there but once I click on something like the tab for full screen and then click off of it I can move my mouse anywhere but if I try again to click the gamma it just minimizes the game and I have tried the resolution but it's so dark that even if made a difference I couldnt tel
Unfortunately I haven't seen anyone else reporting the game minimizing when clicking on the gamma slider, so I can't recommend a workaround for that at this time (if something you try does end up working, please post it so if anyone else has the same problem they'll know how to handle it).
The only recommendation I can offer at this time would be to delete your settings file which can be found here:
C:\Users\YourUserName\AppData\Local\ShopSim\Saved\SaveGames
I hope this helps!
