lift the door, is should be very easy. it will get easier as it goes up. there needs to enough weight on the door so it will come back down.
if it is getting cocked the sides may not be balanced.
check the door opener, there may be some kind of "calibration" as to how far it opens.

There in lies what I believe is the problem. It is not easy to lift and until almost all the way up stays very heavy. The springs are doing little if anything at all. The old door was relatively easy to lift. I am sure these doors weigh much more than the old doors. My guess 100lbs or more each over the weight of the old doors. I believe the opener which I installed new last year when I installed the new doors I believe is doing all the work. The opener has a bar mounted center line on the door. If it is off even the slightest and the springs are not assisting that would account for the cocking in the track.
