Go mule atma stash lost

Not sure if this is the place. I just started using this to help move items across mule for d2r.. I dropped bunch of my set collection into an Atma Stash, but the next time I launch it, it goes (unknown).. There are multiple backups of this file all around but none of them worked. What I did do prior was, I moved where the folder of the gomule was, I doubt that broke anything. What can I do to recover my atma stash or is this a lesson learnt?
