I've done all these every single time. They haven't worked so far.
I'm on Windows. This has been going on for over a year. It will play just fine, then one day it doesn't. This time after an update. At first, I spent weeks figuring out how to do all the things suggested. None of them worked. Then one day, it just played again. Then it stopped again. It won't work for a month or two, then it magically works again. And I've done nothing different. It's really annoying to lose the game for a month or two every month or two, never knowing what causes it, or fixes it. Whatever it is, it's never been my computer. 😠
