Autocal Read Error $0101 No data received

Why am I getting this?


I lost all my files when my computer was rebooted a few months ago, I just added headers to my G8 GXP and have a tune ready to be installed but cannot delete the old read files. I have tried on the auto cal and on efi explorer with no success.

Please help asap as I am going to the dragstrip in an hour!!!!

Thanks, Jay
