Reïnstall, also the single player.
And update your steam.

Try going to the Steam setttings; If you installed the Steam Beta Update (with Big Picture and other things), rollback to the stable version. If not, do the opposite (install the Beta).

What does the Beta do anyways?

The beta is a new and better looking version of Steam that also has some technical improvements that might cause some of those errors or might solve some other errors.
