Thank you, but I have found another way.
I went in to my hosting accounts control panel (cPanel) and at the very bottom was the databases section. In that section was MySQL which when selected to me to the wordpress database with a handy dropdown menu of actions, one of which was RESTORE. I selected restore where I was warned that it would restore the database from a backup taken 11 hours ago and so I took a shot and my site is back up and running.
