Negative Positive
Title: Expired 5 months no credit or upgrade
Review: My wife is a dentist and only needs to refrence this source on an occasional basis. So I installed and used the disk once and tried agian several months later it did not work.. When I finally got around to calling support they told me that they expire the database approx 18 months after the release with no upgrade and no access *** BE Aware** the CD version is worthless after a relatively short period of time.
Is the review positive or negative?
