This is not the right place to ask about that. The game has a dedicated page on itch.io and there is a comment section there where you can ask for support. Discussion in this thread is only about the technicalities of the bundle itself and submissions of games to be added.
Oh shoot, you're right. It's not there, I'm sorry too. I'd suggest to google around for your issue, or to look at the discussions page for it in Steam or GOG to see if people have had a similar issue.
