"When you close PCLink, do you get a window that pops up and says "Abnormal Program Termination"?" No. It closes normally except show pop up window display "cant save...." (forgot exactly) when make some changes to PCLink such as from manual to auto connection. "Can you go to the firmware folder, if the tempqw file is there, can you delete it and try again?" I dont check PCLink folder. We will try again this afternoon. No access to ECU right now (still at work).
