SAVE GAME FILE ERROR

So after editing my save game file for DBD using David Ze's Savegame editor. It worked for awhile and now when i load DBD I get an error for the Save Game file.
Also when I put my file in the Save game editor, it says its not valid. Anyone know why?

you forgot to change the Id on the first tab

It was working before that. I went back into the Editor and gave me more BP - [EDIT] Just put my original file in and this one works.

of course the original will work
