I just bought a 99 Trans Am and purchased HP tuners from the owner as well. I have the cable and have downloaded VCM editor from the website. I'm trying to purchase credits from my vehicle, but I do not have the option in my customer center to purchase credits. On the right side of the screen I have a box that says Download Current Build and Latest Announcements. I do not have the box that says anything about my account credits. When I click on order upgrades I only have the option to purchase Serial Interface GM Lisense Addition and Single Vehicle VCM Enhancement License for $199. I dont see anywhere that I can purchase credits for my vehicle. The previous owner said he had never used the program, said he didn't own the car long enough to play with it. Am I missing something?
