@amit @manton I tried it when the update was available and it still didn't seem to work. I'm giving it another go now and the site isn't updated with the new theme 10 minutes after installation...

Is it me or do plug-in themes take longer to show when compared to the custom theme method? I know I can force a rebuild of the site and that will probably get it to work but I don't have to do that with the old method.
