Hey guys, im hoping someone may be able to provide some insight for me. Ive submitted a ticket to support as well. I?m trying to tune my 2013 ford mustang 5.0, and when i try to flash a file ive already licensed, i get the message ?unlicensed vehicle?. When i try to flash my cars stock file i get the same message. I feel like ive tried everything under the sun to resolve this. I?m using an MPVI pro unit. I was using HP vcm beta 4.3.231 when it happened, i updated to 4.3.240 and got the same results. I uninstalled the program completely, rebooted the pc and installed the newest beta again with the same results. I then uninstalled the beta and installed the newest full version and got the same results. Ive tried deleting the license.dat file from the hp tuners setttings, ive tried resyncing the interface, and also made sure only one valid application key is listed, my application key matches my paperwork and also the one under my account on the HP website. Ive never purchased new credits aside from my kit so i dont believe i would have a new key anywhere, ive deleted and re-added the app key as well. Im kind of stuck at this point and not sure what to do? It will read the file currently on the car but will not flash anything at all. The car will crank and run on the current tune. Nothing weird has happened like an interruption in tuning or loss of voltage or anything. If anyone could point me in the right direction i would really appreciate it!
