I have efi live workshop commercial program. I have had this program since 06 and have had no problems like this. With the workshop edition i have i can pretty program all Chevy vehicles as many times as i want. My problem now is that my computer crashed and when i reloaded the program on to a new computer it is only letting me program 2 vehicles and now i am stuck. I am hoping that a efi live owner or some tech savy person can help me with this. I have a customer coming tomorrow to get there truck programmed and i am unable to do so. I have loaded and unloaded the software several times entered my serial number and all that tons of times and can not get it going. If you know whats going on and can help please do so. I dont know who to get ahold of on this i have no phone numbers. those would be cool to if you can get a number to efilive somebody. thanks again kind of jumbled up but kind of in a hurry.
