I've had to download it manually by google drive page, it's ok now. Probably because it's stored in a google drive webpage link that itch launcher didn't got it correctly and gave me the "?" file size (-1 as an error to get the file). This itch launcher i'm using is on Epic Games Store, but can be downloaded by itch.io website. It can update the game files automatically to everyone that downloaded it after an Update or Fix.
