Problems with tuner..

[13SRTRAM]

I have a T1000 and i used it on my 13 Ram 1500. The tuner had been off the truck for months, and i hooked it upto my 2010 camaro ss and tuned it without having to unmarry it from my ram. Well now im selling my camaro and have been having some crazy things going on. First off when i tried to remove the tuner and go back to oem the tuner wouldnt even come up it kept telling me to turn the key on that it wasnt connecting to the car. Then a guy from support told me to update the tuner and that it would need to be force updated. Well i went home and downloaded the new software and it downloaded with no problem. So i told the tech guy and he was surprised it let me since it was supposed to be married to my camaro. He told me to check the last tune and it said it wasnt married. So he told me that it should be good to go and i could now use it on my 2014 Ram1500. As soon as i hooked it up it told me i needed to update and that it was married to another vehicle and so i checked and now it has my camaros vin number in it. Can somone tell me what is going on and how to fix it. Thanks
