Whatsup

My husband is using Windows 7 with EI 9.  I have downloaded Flash Player 14.0.0.125.  My husband uses the EI for viewing his You Tube videos & playing his Online Video Games.  For the You Tube videos some work & some don't work & the ones that do not work state "Please download Flash Player".  He has not been able to play some of his Online Video Games & some do work.  But his favorite ones that he likes do not work.  I have checked my Manage Add-ons under Toolbars & Extensions for the Shockwave Flash Objest by Adobe Systems & it is enabled. I also use Google Chrome to play my games on Facebook.  The games are slow or freeze up.  I could deal with that but my main concern was for my husband using the Internet Explorer 9.  I always update everything & we always clear our Cache.  I am missing something or is there something wrong with the Flash Player.
