My response would be to disable pepperflash or do as Alosso stated.
But if the only flashplayer you have installed in Chrome is the pepperflash player then you will need to install another flashplayer in order for flash applications to work.
1.) Click THIS link to go to Adobes flashplayer download page.
2.) Uncheck the offer of a McAfee security scan.
3.) Click the install now button.
4.) Save the flashplayer installer app onto your computer and remember where it is saved.
5.) CLOSE YOUR WEB BROWSER.
6.) Run the flashplayer installer app you just saved.
7.) Select your flashplayer update option.
8.) Go to Chrome plugins and disable the pepperflash player.
9.) The end.
