Dolphin browser app help

[tablet2011]

I have the Dolphin browser app on my tablet and for some reason today i have gone to use it to find all my bookmarks have gone.

So is there anyway of getting them back without the need to put them all in again? as i dont understand why they have all just gone like they have.

Did u install any apps like move bookmarks to sd or something similar??
