Yeah, I've seen this before, I just don't really know the cause of it. Make sure that you have the most up to date version of the game (major update 1) and maybe try redownloading it. If that doesn't work, I'll look more into it. If you could share the error message with me, that would be great.
As I was reading the error, it showed there wasn't a certain png in a file or directory in the folder within the AppData folder with the main.exe in it, however nothing else. So I copied and pasted the files from the .zip except for the main.exe into the file, and it worked perfectly. Thank you. You asking me to read the error lead to my curiosity to the problem. I had a sigh of relief that it wasn't something wrong with the code. Have a great day :).
