I'm not entirely sure what you are saying here. When you download the newest version you can't open the game? As in the game crashes before reaching the start screen? Even though you mention above that you installed version 0.37?

when i download the file 'CiC 0.37.12 Mac.zip' and try to open the game i get an error that reads "The Application 'Game' Can't Be Opened." The older version i still have will let me open the game but I get the error that I posted above when i try to install the new patch. I believe I did it correctly but I'm really not tech savvy to be completely honest so maybe there is a mistake im making...
Ah okay, if you're on Mac then you probably need to move the newly downloaded version of the game to your applications folder, or edit it's permissions so it has read/write permissions. This link can help with read/write permissions. https://support.apple.com/en-ca/guide/mac-help/mchlp1203/mac That's probably why the old one works and the new one doesn't. (Side note, if you are applying patch 0.37.12 to a base game prior to 0.37 when you mention patching it, that will almost certainly cause errors.) The other thing you'll need to do is apply the "old save compatibility patch" to your game. That should solve the first error you posted. (If you get to the fifth dungeon, you'll also want to enable compatibility mode with the debugger, if that gives you a bug you'll want to apply patch 0.37.13.)
