Just download chapter 7, it has all the files you need. Unzip and run. Saves are stored on your computer separately and will automatically appear in your game.
You don't have to pay anything because I paid for MEGA myself, and 90% of the download comes at my expense. The free download limit covers the remaining 10% for each user. So everything is done for your convenience:)
And there is GDRIVE for those who can not use MEGA.
