Unityplayer.dll is missing

I bought the Overwatch game. It was fine until yesterday but today I am getting the above error. But the unityplayer.dll is already present in the installation directory. Kindly suggest me a quick fix? Thank you.

Have you tried to uninstall the game and install again? Maybe something (an update?) caused a file collision. Try it and let us know! Have a nice day!

Post in overwatch tech support maybe?
