Hosting habbo retro on godaddy 404

[BackSlashx00]

I had many issues hosting my retro on godaddy. Please do not tell me to change to another web hosting domain, all I care about is hosting the website not running the emulator. I called Godaddy 3 times, and all led me into different approaches which at least got me close enough to seeing my website, but not the index. Every time I enter my retro domain I get the following:
Not Found

The requested URL /index was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

---

Apache Server at RetchHablet.com Port 80

If I were to enter RetchHablet.com/register or RetchHablet.com/404 I can see my website, but if I enter the domain alone: RetchHablet.com I will get the following above "Not Found" 404 error. I am assume it has something to do with index.php?

What can I do?
