Ok thx, that worked
but now it says this:

Native Client flag is not enabled. Please go to about:flags, enable Native Client support, and relaunch your browser.
I actually don't know where to find it
Just open a new tab, in address bar type about:flags press enter, this will bring up a menu which you enable 'Native Client', close browser down and open back up. Then just try the link below, (From OP)
