First of all is your model combined properly and your verts merged?? I know this may sound like such a fundamental question but its quite common mistake when you are learning and tend to overlook things J yes I believe they are one of the reasons I believe that they are is because when I select the edges manually in the UV editor for each section that matches along an edge the same edge is selected on the model just not on the corresponding piece that shares the same edge I even tried to do an auto mapping to see if I was missing pieces and still I was not able to get matching edges to be selected much less to sew them together.
