So... what game was it, and why do you think this has anything to do with itch.io? Sounds like the file was deleted accidentally. Could be your antivirus. Try getting it from the game archive again?
I figured out a little while ago and fixed my antivirus but I still don't know how to get my progress back once it's done downloading
I don't know. Maybe you could just get the missing files from the archive, instead of unpacking the whole game again?
