You need to download the game from your itch library.
Go to your profile->My library.

Are you talking about the itch app cuz if you are, there's still an issue. When i click install or even click on chapter 7 file, it just shows chapter 5, no other option

Just in the regular website.
If you bought the complete edition of the game it should appear in:
My Library-> My purchases
And you should be able to download the game from there with no problems.
The "This title is hosted on an incompatible third party website" message, I've never seen that before. But the game is hosted in the same server as always (The public version as well) so it makes no sense.
