I just attempted to cal flash my 07 HHR to turn traction control back on only to discover that it (V2) wants to use another license. I read through the forums here and followed what others have said about unhooking the v2 and starting over, checking firmware what not only to find that I am up to date with everything. The car hasn't been to the dealer for any repairs, any thoughts??? I don't really want to buy another license for the same car/controller.
