Contacting TR is a good suggestion. Some others on here found an issue where centershot was in between two of the screw holes and TR made a special mount for free. Give them a call and see what they can do for you. Their customer service is top notch.
I was one of those guys, and they helped me out without even questioning the problem. Go on their site and get their phone # and call them, I am sure they will help.
