Help with Gibbed Borderlands 2

hello i have release r146 of this editor but it doesn't work.
I open file and i obtain message like "failed load save:invalid or unsupported version"

Can anybody help me?
Please

 

open your save on horizon and go to contents and then extract the save from inside the contents tab

 

Of course i did this and i try to edit SaveGame.sav but i obtain that message anyway.

 

OK i fixed it thanks
