My 2013 Office Pro started acting up on me this afternoon; all morning it was find. Now, I'm talking in ALL applications (Access, Excel, Word, Outlook) the ribbon bar (if that's what it's still called) became twice as large in length & width. Ok, uninstall & reinstall 2013 Office Pro. I can't reinstall 2013 Office Pro; Microsoft doesn't recognized my Product Key. Microsoft talks me into buying another Product Key & some other online support BS. After I download my new version of 2013 Office Pro the d*mn ribbon bar is the same. I feel like I'm crazy but I'm not; I know that the ribbon bar was smaller & more compact. Now I can't find how the h*ll to find out if I can get a refund; I'll go back to 2010
