Unhandled Exception Save Editor

Everytime I open the the save game editor, found here https://www.mpgh.net/forum/showthread.php?t=1343336, I get an unhandled exception error.
It also occurs when I try to save the file over the previous one.

Has anyone else had this issue?

need EAC bypass first

I already have. I used windows firewall to block the outgoing DBD process, and deleted the roaming EAC. Still does it everytime : /
