When Access opens, it sets up a *.ldb which locks access because it thinks
someone is using the programme. When you exit Access, the *.ldb is normally
closed unlocking the database. It is possible in certain circumstances that
the *.ldb is left open.
look in the same folder where the database *.mdb resides and see if the is a
*.ldb left open. Ensuring that no one else is logged in and that you have
backed up the *.mdb, delete the *.ldb which should free up the database again.
