I also have the same issue with a E67 ECM (create engine and controller from GM for a river Boat), the ECM was previously tune by another tuner. I down load the file and save it, It states that the checksum have been disabled.
EFI is up to date but i get the same error (Script exited with code $06FF: Checksum failure.) even when i try to upload the original file before i modified it. The one thing i noticed the when you try to upload it shows that the VIN is all 00000000000000
Any help would be appreciated

I see on other threads you were able to fix the file to be loaded when some one else has tuned the controller before, would you have time to look at my file?
did you look at post 30? read and try GMPX's advise... It worked for my issue..
