Problems with duplication

Hi John: I’m having problems again. I made some changes and it’s stuck on “STARTING ON L40S”. I deleted the duplication from my private account, went to your account, accessed your Difueraser Demo Mini, and duplicated it again to start from scratch, but it never finishes. It’s stuck on “Starting on L40S”. It’s strange because the duplication worked yesterday and now it doesn’t. Sorry for the trouble.
