sorry to hear that you still have problems. Installing the Plugin using the URL
https://www.max2play.com/download/15362/ should really do the job for you, but obviously it doesn’t. As the system had to deal with several unsuccessful installation attempts over the course of the last few months, we cannot exclude the possibility that something is seriously broken within your image. In this case I see no other option than starting with a newly burnt image again.
