There might be some other plugins around with the same functionality. If you like those skins you can import them I think, not the easiest task but shouldn´t be a rocket science.
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.
