I got it to work. Write “about:plugins” without quotes to your address bar in Chrome. There should be two Abobe Flash Players installed (on top of the list). One of them comes with Google Chrome (Type:NPAPI), other is not (Type:PPAPI). Disallow the one which is installed by you or Win updates (Type:PPAPI). Conflict between these two is the reason why ProPlayer doesn′t play in Chrome. After it′s done restart your Chrome and it should work well.
Please give me some feedback, if it won′t work there can be other solutions available. If you have any cache plugins installed then most likely it would cause conflicts with other plugins. I suggest you to uninstall cahce plugins then and manually gzip your content via .htaccess.
