Lost my album path

I'm going to play my blonde card, I can log into this website, but have no idea how to get to my albums, to edit, view pics, etc. I recently changed my web host as I had probs with the old one. My website is up & fine, but can't the links do not work.
So I typed in what I thought was my address for my album, but it comes up with a 404 error message, does this mean I have lost my albums?
I think I have gallery2.
Really hope someone can help me! xx
