Object reference not set to an instance of an object in VS2013 Form Designer

I'm trying to covert old VS2003 project into VS2013 with .Net Framework 4.0. In original VS2003, all forms in this project could be displayed, but when I converted it and tried to open these form designer in VS 2013, I had a error as "Object reference not set to an instance of an object ", Please see the picture below.



Also, I searched some similar questions in forum said "the data format in .resx file was inconsistent with high VS version against VS2003, such as need to use <value></value> if the value in some filed was null". I checked and tried this way with my code but still not working.. So, please give some advice if any other reason for this kind of problem.
