I sorry to hear that you can't play.
How are you going about launching the game?
Have you extracted the executable from the zip folder?
I don't have enough information to understand the problem you are having so I can't help you that much.
sorry :(
I tried downloading the game through the desktop app and for me it worked fine.
I don't use the desktop app so I don't really know how to fix that problem.
You can try uninstalling the game or deleting the game and its contents from your computer and try downloading it again.
If that doesn't work I think you will just have to go to the website and download it from there.
sorry I couldn't be more helpful :(
