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

of course the original will work

A lot of people are having this problem, my friend is getting the same problem. I'll have to ask him what he did to fix it. I'll let you know.
