If you touch ANYTHING on the car while it is working it will mess up.
You need to start by rolling your window down, close the door, stand out side of your car, plug in the tuner, start the upload and walk away.
If you do anything, from opening the door touching the stereo or even turning on the lights will throw off the tuner.
I learned this a long time ago when I thought I had the same problem than the SCT rep told me to do it that way.
