I cannot get the movie to play beyond 13 seconds. After installing all of the extensions again have you gone back and deleted the cache file again? You should make sure to do this after you have the extensions installed.
Are you getting the same error you were getting before or is it a new error? If you can post back and include the details about the steps you are taking or if you can post a video or screenshots of the steps you are taking it would help us to determine if this is part of the problem.
