Aura KoboReader.Sqlite help (stats lost)

Hi,this is my first message and i hope it's the right place to ask.
Yesterday i lost my reading life stats (hours and books read). I had 233 hours and 22 books and now i have 134 hours and 10.
I know that this info are kept in the file KoboReader.Sqlite
I tried to open the file,looking for the parameter that have these settings but i didn't find them.

So i was asking
1) Does Anyone can upload for me his KoboReader.sqlite file if has similiar stats with mine ? (233 hours and 22 books)
2) Is there a way to edit the file ? I don't want to "cheat",just restore my real stats.

Thanks :) Sorry for my bad english.
