Without new Installation.
How the importer work's, I don't know.
Importer had created 1 main-cat = Meine Videos, but put the picture from an other album in it.
It would'nt delete any original-cat, album "Mein 1. Album" was put without a sub-cat in main-cat, other albums would go in sub-cat from A-cat and so on
But now it work's
Thanks
P.S.: Hope that my daughter would use it and not cippermine
