Give Firefox or even Microsoft Edge (I know, lol) a try real quick and see what happens.
If it's still not downloading, you can e-mail me at darkchibishadowdev@gmail.com with a screenshot of your purchase and I will get you any files you want. 👍
So bad news: neither browser worked. Good news: I switched devices and it was ok then? Except for Episode 7, that one I can't download no matter what I try, for whatever reason. I'll try to reach out via email soon. Thanks for all of the help!
