Like I mentioned in the other Thread...you need to edit the valid expression column in the Links.def file. Either remove the valid expression (you may have simply copied another field config like CategoryID for those other fields).
If you manually edited the .def files, then that is your problem...I have made many mistakes manually editing the .def files.
