Would you mind DM-ing me too please? Guess it possibly doesn't bode well for the future though...

Yeah I'll send it across. If they don't respond I'm just going to post the plugins publically (they're GPLv3). Unless Bunny changes their API or Wordpress significantly changes, there isn't much that could cause the plugin to stop working and it doesn't look like too complicated a plugin so I could probably fix it anyway.
