Are you positive you are the only user in the database? If it's on a network drive, try copying it to your local hard drive, doing the compact/repair there, and then copy it back to the network. If it's on your local drive, try rebooting your computer, deleting the .LDB locking file in the same directory as your database (if it exists) and compact/repair again.
I know the original question was posted half a year ago so this is too late to help the poster.
If there is no .ldb file, the database is copied locally (so no possibility of it being locked), you can't repair and JetComp (download from Microsoft) also won't repair then your database is corrupt and the only way forward is to restore from a backup. Sorry.
