I just bought a 6021 hp tuners pro and done everything it says to do. Got the software loaded everything works fine as far as on the computer. Connected my obd2 cable and everything on the car and to the computer. Hit Read and the interface now wants to update the firmware on it. It stops part way through with the part that says trying-1, trying-2 ect ect. then gets a fail message. Try unplugging it reconnected it same message. Restarted my computer with nothing connected and plugged the USB back in hit read again and it went further and said erasing or something like that. It failed update again and then says invalid application key even though when it pulls up its obviously the same one I was givin on the piece of paper along with the serial number. Now everytime i plug it in and hit read it says invalid application key. What am I doing wrong or what do I need to do. I'm more than frustrated at this point as I would love to get started on my car. The .net framework is also up to date. I'm confused as what to do at this point. Also the interface has the error light and the power light. Like its stuck between erasing and updating. My computer is vista, and 3 gig ram ect. Dont think its my laptop, but yet i have no idea. Just want this problem solved ASAP. I have a newly built turbo car I cant do anything with, at this point I have an expensive interface and a awsome tool I cant do anything with. PLEASE HELP ANYONE!!!!!! Thanks in advance for any advice.
