Yes, I was flashing the PCM fine and then FlashScan changed the serial# to 00000's and then it went thru the bootloader segment and issued a new serial# which was totally different from the original serial# & that's when FlashScan didn't recognize the serial# and asked for another Vin License.... I went thru this about 3 different times before I gave up.... Each time I tried to flash the PCM, Flashscan would give a different serial#
