Just make a basic new ID file as a test, toss a few commands on there and upload to your remotes and processor. You may also try using a different laptop for the test programing. I have had a few laptops over the years that developed usb problems leading to incomplete file transfers. My current laptop is on its last days and is starting to refuse usb transfers so it is time for me to once again break in a new laptop.

by the way, I just installed 5 T2C+ remotes with an XP6 all of them work fine.
