QSC8.3 CM554 CAPS - How to get .xcal file

[J99]

I need to recalibrate my Engine which is not starting anymore due to ECM recalibration need showing in Insite.

I got an official Cummins ECM Calibration file (J91384.ENI) for this QSC8.3 CM554 but it is password protected (when unzipping) and I can't see it in Insite 7.5.
So following advices on your forum, I am trying to get the .cal or .xcal out of it to be able to use it with Calterm.
But when trying to unpack it with Incal v4, it fails with a "PW Error".

So I was wondering if using {a cal converter program} would help me there (or if I risk to get the same error) before purchasing it online.

If someone could help on this and how to get me to this .xcal or .cal file, it would be great !
