Well I just completed my download of 4oD and encountered some of the same problems as others on this forum. Yes, i received the horrible error 1904 and I have followed all the steps on this forum. 1) uninstall flash then installed flash 9. 2) uninstall 4od and re-install. After completing these steps all I get to view on 4od is the media player screen appearing once I hit stream now and then once buffing is complete it says ready then the media player closes. Hence I have not watched anything bc the player closes before anything starts. Does anyone have any advise?
