Darn, sorry to hear that. Can you try running from CMD with .\petsitting.exe --verbose and see the output there? Or if you haven't already, try running as administrator?
Hey, thanks for replying back! I did try running as admin. I also tried petsitting.exe --verbose and do get an output.
EDIT: I figured it out. Apparently the output said a certain program could be causing a conflict. Uninstalling it fixed it. Thank you so much for the help! I really appreciate it. Now I can play your game. :)
