Are you 100% sure you don't have your database set to create a backup of itself when opened ?
If you do, and it crashed, there will be perfectly working copy of it in the same path where you where running the database from. It will have a ~1 on the end of it or some other number depending on how many times it crashed.
Beyond that, I cannot think of anything other than going to the server backup. Surly there's one there.
