Here are some questions I need you to answer:
Other than the room files, what have you placed or replaced in your media server?
Can you send us a screenshot of your developer tools console? (F12 > Network before you login, and leave it open)
Are you forgetting to replace game_configs.bin and/or party.swf with one that's compatible with the partly?
