I would go back to the dish and start over. If you dish is off and not aligned properly you can reset your receiver all you want you will still be in the same place.
Make sure your pole is absolutely plumb, and that it is a stout enough pole not to go out of plumb as your dish goes east and west, with the weight of the dish pulling on the pole.
Set your LNBF skew to "0".
Set the latitude setting on your motor to your latitude and lock it down, don't touch again.
Set the elevation on your dish per the formula in the manual that came with your motor.
Using a compass rotate your whole motor dish assembly on the pole pretty close to your true south, leaving it snug but loose enough to move.
Now hook up your receiver to your motor, set your proper lat and long in your USALS set up.
Critical step that newbies miss: Go to 83W..."Motor Moving" should come on the screen. Unless you are exactly on 83.00 where you live, it will move a little but not much, but it will still move.
Now go out to your dish and using a meter or a small tv/receiver at the dish so you can see what is going on. Select an active transponder on 83W.
Now rotate the motor/Dish ass. on the pole ever so slightly back and forth. No Signal? Change elevation on your dish a bit one way or the other and rotate again.
Repeat this until you find a signal and then peak out the signal by rotating the motor on the pole and changing the dish elevation in small increments.
DO NOT MESS WITH THE LATITUDE SETTING ON THE MOTOR(sometimes you may have to move it a hair, but for now leave it be), just peak by rotating on pole and elevation on dish.
Now tighten everything in a rotating sequence. If you tighten one bolt that holds the motor on and not all a little at a time until they are all tight, you will pull it out of level.
Now hook your receiver and and LNBF wires back up and go in the house and try a few birds, you should be tracking the arc pretty well at this point.
