I've just upgraded to the new version of Media Box on my N810, but when I start it up, nothing happens. I can see that 'python /usr/bin/MediaBox' is running, but it never appears on screen. I've tried removing all the media-box related add-ons I had before, and removing and reinstalling several times, but to no avail. I've also had the battery go flat very quickly a few times since installing it, which I see is also a known problem.

Is there any way to install the previous version, which worked fine for me? I'm about to fly to the US, and I was planning to watch some videos on the plane.
