We're so sorry that you had difficulty installing this door, Floyd, and we do apologize, too for any misunderstanding!
It is critical for the longevity of your door to use the high quality, sturdy nylon screws included with this door. This is because these screws are able to provide flexibility, adjusting with the natural shifting of the frame over time due to temperature changes and time, etc. If metal screws are used, the frame of the door will become damaged over time due to excess strain. We're so sorry for any confusion.
We would love to discuss the current situation with you directly to see what tips may help increase wind resistance for your situation. So that we can do so, please reach out to us. Our number is 1-800-732-2677, and our hours are Monday through Friday 8 A.M.- 8 P.M. EST and Saturdays 9 A.M.- 5 P.M. EST.
