It’s all gone!

Yesterday, I added WordPress to my account through my server, Liquid Web. All was fine. I posted my first blog, linked to it through the home page on my website, wrote two other posts for future delivery. This morning, it is all gone. I can no longer access my wordpress account using the passwords and user name. The hyperlink no longer works and the error message says it doesn’t exist. I didn’t do anything to change this, I don’t think. Has this ever happened to anyone else. If so, what the heck happened.
Thanks!
