I recently downloaded the cube world demo to make sure that I can run it smoothly, as which Picroma recommends. And one of the requirements to run the demo and play the game is to have DirectX and its newest version. But everytime I run it, it says that you need to have DirectX. I have tried deleting and reinstalling and the same thing happens. Thank you for reading and help would be much appreciated.

Note: I would post it on their forums but you can't because they keep getting hit offline.
