did you log a ticket, i have the same issue with 2010 NGC4 from Ram 1500. Seems that the new release had a bug.

Potential Tuner
I previously reported this error request ticket #25512.
I am not to pleased with the answer. I have contacted the previous owner regarding the problem, unable to use the Tuner. He in his turn is getting a hold of his brother, whom is currently in possession of the old Tuner.
I feel like I am left out to dry, as per packet " if opened can not be returned". Prior to purchasing the device I did some research on it and nowhere does it say if your vehicle has been previously tuned using HP tuner. You have to contact previous owner and try to figure it out on your own.
Hope you understand my dissatisfaction purchasing a $360 device that can not be used.
