Cannot Open Access 2007 MDB file

I have an Access 2007 file that I was working on at my office. I left for the day and the database was still open. When I came back the next day the system had shut off so I rebooted (no issues). I tried to open the database and am getting the error message: "Unrecognized database format 'C:\....\filename.mdb"

I cannot get into the file, I cannot Compact/Repair it either. Anyone have any suggestion on how to get the data "out" I have tried using Access External Data, Creating an new DB and importing the broken file but I cannot get past the error message.

I can open previous versions of the same database.

I really need to get the data. I can attached the file if someone can figure out what to do with it??
