Because Chrome comes with its own Flash plugin it takes a couple of quick steps to get the debug version of the player working.
Before anything ensure the Plugin content debugger is installed. This is downloadable for here and the currently running version can be checked here.
Next load up Chrome and go to about:plugins from the address bar.
Click on the Details button to show more information about each plugin and scroll down to the Flash plugin section.
There should be two plugins listed. Simply disable the one in the Chrome application data folder (probably the first one) and the debug player will be active.
