Civil 3D Points

[DWILPAT]

has anyone else worked solely in Civil 3D 08 then switched to AC08 with Carlson as an add on? if so, maybe you can help. I have approximately a years worth of Civil 3D .dwgs and have recently switched to Autocad 08 with Carlson Survey 08. When ever i open any of the Civil 3D .dwgs, in Carlson.... None of my points show up!!! None... notta one. I understand Carlson and their .Crd files... thats not the problem. My Civil 3D point blocks dont show at all!!! can anyone help?
