Like others have said.  First, "Face or Nuts".  Then I would call Mathews and very politely and humbly tell them your story of what happened.  Let them know exactly how much you love that bow and how much time you spent to find that cam.  Be very nice.  It's worth a shot and who knows, they may take care of you and since you're already expecting a worst case scenario of spending money, it's not going to hurt as bad if they turn you down.
