As someone who has also been seeing this error, I can say that Ignore is unsuccessful. It pops up again instantly, and then the game crashes to desktop.
I did notice something odd with DirectX. When I ran the diagnostic tool you guys provide, it initially couldn't identify DirectX 9c. I went ahead and reinstalled that particular DirectX, reran the diagnostic, and it was able to identify it. Then I tried playing the game again, got this error message, same as always. When I ran the diagnostic a 3rd time, it again wasn't identifying DirectX...
Don't know if that helps, but thought I'd mention it.
