Hello,

I have a few questions in order to help narrow down the cause of this crash:

  • Could you please provide the logs from your project’s Saved->Logs folder?
  • Are you getting a Crash Reporter window? If so, could you please provide your Machine ID from the window and ensure that you hit Send on the window?
  • Which class are the files that you have posted included in?
