If its an Access 2007 or newer MDB I don't know of any other than brute force to get at that one. If it comes to having to pay for something these guys are good: http://www.elcomsoft.com/aopr.html If you're stuck with brute force at least that one lets you use 32 CPUs or CPU cores and up to 8 GPUs so it don't take forever.
