If you get this message after you enter your password, you probably have
downloaded and installed a database of a different date or of a different
database edition than the one corresponding to your individual password.
You should check again your password email and make sure that you are
downloading the correct database. For example, if your password is for the
9/30 Personal database, it will not work with a database of any other date
(e.g., 8/31) or edition (Pro, Pro Plus or VA).
Simply download and install the correct database and your password is sure to
work.
