Have you read the directions? Not trying to be a smart a$$ but there are a few different ways to hook it up/ get it to talk to your PC. One way you hook it up to update firmware, another way to load tunes or download the stock tune. I messed up a few times before I found out what I was doing.
Do a quick search for "download stock tune" or something like that. The SCT folks wrote directions on here for us. You can go the the SCT site for directions, manual, etc. You can also call SCT. They have good customer service.
i bought mine off of ebay too and when i got it and tried to put tunes on it wouldnt work so i called sct and i had to download the new live load ford program and updated my device and since then it works as slick as pam spray on a snow sled
