Check in my my accounts link. If it is on the list there, it will be in red. If not, sorry, you are going to have to start over again. I like to save my work from time to time just to make sure things like that don't happen.
P.s. I also write or save all my hubs in a word file, so that if anything happens online, I still have it on my hard drive. Plus, it helps me proofread for spelling and grammar.
