I'm not going to claim this is the answer, because I also stopped (completely) and re-started Android Studio after I installed it, and THAT might be the real solution, but Ads were running fine on the emulator and a USB-attached 7" tablet, then I started getting this error. Checking my SDK packages, I noted the Google Web Driver was not installed (this had not been an issue previously) - all other components were (except the USB driver, which is not needed on a Mac). I installed this component, stopped (completely) and re-started Android Studio and the ads started running without error again. It's something to try, anyway.
