Two Blogs Disappeared!

I’m not sure what happened. I don’t sign on or post that often, probably was a couple months ago, but 2 pretty in depth blogs are now gone. My sign on exists, but says I have no blogs. I can’t even get into dashboard, they just don’t exist. Even my gravatar image is gone.

I did get a new computer in that time, could something have changed? I have no clue where to begin, but I don’t like that my blogs are gone.
