Can't update driver to the correct version. Need help!

Sorry guys, I'm not super tech savvy so you're gonna have to explain it in pretty simple terms to me. But what happened is I got a new game, and when I launched it I got this message:   "The installed version of the AMD graphics driver has known issues. Please update to the latest driver version.    

ATI Radeon HD 4600 Series

Installed: Catalyst 13.9

Recommended: 16.300.2311.0


I tried to use the automatic updater system that the AMD site provides, but it only installed me with the catalyst version. Any help would be great!
