I tried downloading "Buckshot Roulette" and the file came up blank. Just an empty file titled "9485738"
When I tested other games I got the same result just different numbers. How do i fix this???

I know several people have downloaded that game, so I don't think it's a problem with the file itself.
Maybe it's a problem with your ISP, try downloading the game from another location or using a VPN.

If you still have the problem, it may be best to contact support
