Exclamation [Q] Rom toolbox pro not restoring app data ?

Hello, i did full back up of my apps and their data before installing a new rom... and copied the data to my pc and then after installing the new rom

" Gnabo v4 " i copied the user_apps and app_data folders and i was only able to restore my apps without DATA ( my saved games and other stuff)

So please can anyone help to fix this ? or is there any other app that read the files (.tar.gz ) in app_data and help me restore them or a way ??

Thank you very much
