I keep getting an error message. "Important_Asset_Missing" followed by: "The game tried to load a File but it was missing. Unfortunately this may cause the game to crash. We're going to try to automatically rebuild the file the next time the game boots up. Sorry for the inconvenience!" I can get to the load screen but it freezes at the loading screen. I've removed it and downloaded it again but I'm still coming up with this issue. How do I fix it? - Mac User
