Google Chrome Cooliris add-on Crashing

I downloaded Cooliris add-on for Google Chrome and at random times, the browser freezes and after a few seconds, it says Cooliris has crashed. Any way to stop this problem?

Make sure that the browser is up to date or the most current.
Make sure that your graphics driver is up to date
(Go to device manager and look at graphics driver)
Make sure there are no yellow warning markers in device manager.

Can you tell me how to do that? I found device manager but cannot find the graphic driver
