Sorry that didn't work.
I've passed your log file onto the team. I'll let you know once we have any more information for you. Thanks for your patience.
Edit: Based on the error in the log, it looks like an issue with Unity, the game engine we use. They have supposedly fixed this bug in their latest version, which we'll update to very soon. Fingers crossed that this will solve your issue. We'll let you know once we release an update which uses the newer version of Unity.
