Hi, once you've made the payment, you can download it as many times as you want. If not through this page, you can go to the "my library" tab by clicking on the arrow next to your profile. There you should find all the products you've already purchased. Let me know if you still can't access it.
I don't know what the problem was with itch.io, probably It was that error that occurred on the international Cloudflare servers, it took down a lot of things,like Twitter and etc, in my country it was only resolved recently, but I can send you an access link, but how? Because if I post it here, someone will take it.
