Sorry I did not post here sooner- been busy with the holiday! At any rate, your door is probably "cocked" a bit, due to an impact on the catcher somewhere. When you try to shut the door, it probably is hitting one side or the other of the frame. Just open the door about 2 inches (at the base), stick a bar or some sort into the side that is too far over, and give it a good yank towards the center of the door. This will bring it back into alignment. If the problem is at the base, take the door off and use the handle end of a steel hammer to give one sharp rap to the bottom of the frame (this will bend it down just a bit). Give us a call if you need any other help.
