Recently wanted to try Hyper Scape again for the first time since beta so I downloaded it. Clicked play and it looked like it was launching but never actually opened up, it just stayed open as a background activity on my pc. I tried installing the ultra HD texturepack to see if that would magically fix it but only made it so that it doesn't even show up in my task manager anymore. I've tried verifying the files and reinstalling the game, but I still have the same issue. Unsure of what to do.
Can you go through the steps found here, and let us know if you're still experiencing this
