Before you send the ESC back to us, please check your PM, I have give you one final back check from our software and hope that will solve your problem. Your ESC looks like it has the software upload failure while uploading and it scratched the file upload, it is a software issue and I hope my PM will give you a good upload (reformate) and resurrect your ESC.
