Keep stuff before clean reflash

[supernano]

I hadn't used XBian for a while. Now I started using it again and had a lot of things to update. Something went wrong along the way and I believe my card is now corrupted, as I keep getting errors when trying to update.
I would like to do clean reflash with the latest XBian image, but it would be great if I could salvage some of the configurations/addons/favourites/licenses/etc that I have before reflashing. Basically save as much time as I can reconfiguring Kodi to my liking. Is there any way to do this?
