Having trouble with modding Payday 2

[Lvzx]

Iv been trying to mod payday 2 save with this: http://www.360haven.com/forums/threads/26933-New-GUI-PayDay-2-Save-editor-V1-0-0-3
But I get a error: http://gyazo.com/0f0713ab4794b4337fbfd59c2c15e00b
Is there anyway to fix this?

You're getting that error because of the update to Payday 2. Saves made on the new version of Payday 2 cant be used with the editor until Jappi88 updates it if he ever does.
