Look at the symbol above the wrench icon. That usually means there is an update available and it can't be installed until you restart. Just go to "About Google Chrome" and it will check and install any updates. After that, it will provide an easy button that will restart the browser and reload all your tabs and windows (the other option is to completely close out Chrome after verifying updates have been successfully installed).
Also, what extensions are you using? Some have been known to wreck havoc with plug-ins.
Google chrome says its up to date now, Java, and Flash are both up to date. My extensions are proxy switchy and adblockplus. Game still doesn't load even when I disable proxy switchy.
