Cadillac SRX 2011 Script file not supported

Hello there,
I was trying to read a Cadillac SRX 3.0L 2011 with E39 ecu, but I got this error: "Script file not supported by current software version".
My software it's updated and there's communication between ECU and laptop, it recognize the ECU correctly.
Any help in how to fix this ???
Thank you in advance.
:shock:

It's likely an install problem, try uninstalling and then re-installing V8. That will commonly fix this.

And make sure you use the latest release on the main EFILive.com downloads page. I believe you cannot use V7.5 to flash the E39 and must use V8.
