Open a crd file? I assume that you are opening the drawing, then going over to the POINTS tab, then down to the SET COORDINATE FILE selection, then clicking on the EXISTING tab and then double clicking the desired crd file? Then you can import, list or edit the crd to your heart's desire.
If you still get that error message following EXACTLY the steps above, you may have a corrupted file. If so, a reload of the latest build of your version may be required.
