Resolved Diablo 3 save Object reference not set to an instance of an object.

I am having issues when i am extracting my hero to edit the the hex code to get my weapons better.
I got a message like this

Object reference not set to an instance of an object.



I've uploaded my save file, please help

When i press the "Extract" button and picked a place to save it, this shows up.

 

Seems to be a issue with the 360Revolution client, because i downloaded a pre-downloaded uploaded working game save and it didnt work
