I know this is an old Post, but just in case, like me, you have this problem & end up here looking for a solution. This is the solution that worked for me. Go to the Manage Tab, then go to Locations. Pick one of the locations listed & make it current. this allowed me to detach the Cad link & re-attach it.
Hope this helps someone.
