hi , could you upload a different platform to download the game , because if you are a free user of Mega , you are allowed to download only 800MB if I´m not wrong
I was about to say thet same as tealheart9 said (but with 7 days of delay 😅).
Another option and the one we usually recommend if you want to use Mega, is using a free download manager called j-downloader 2. This one allows you to download from mega ignoring that browser cache limit thing.
Hope this helps 😉
