I will guess that you have the locking hub out. which is the outer shell with the handle that you select lock or unlock, probably a spring and a gear and then what I will call the internal hub which is the part that the allen screws attach to.
I would look for a clip on the interior of the hub along the outer ring. Just clean it with a rag and it is made of round wire and there should be a gap in the clip and lightly pry on it with a small screw driver and pull it out.
If you have more questions let me know. I just happen to have my hubs out right now in the garage and the rotors and knuckles off.
You will need a hub socket to get the locking threaded washer things out. they are round with 4 notches in the outer edge. After you take the first one there should be a spacer that will slide out with a little moving around with a small screw driver and then undo the other locking threaded washer. After that the whold rotor will come off the spindle, don't drop the bearing out the front of the hub. then unbolt the dust cover and wiggle the spindle off.
Hope it helps.
