Currently you must download the latest database from the following location (you will get redirected to a Google Drive folder):
http://peqtgc.com/releases
The filename will be something like:-
peqbeta_{Date_and_Time}.tar.gz
where {Date_and_Time} is actually the time it was generated e.g 2014-04-01-02:01
Next, go to the folder C:\EQ\SQL and unzip the file.
If double-clicking on peqbeta_{Date_and_Time}.tar.gz does not launch 7-zip or your preferred unzipper, you may need to launch 7-manually (possibly using 'Run as Administrator' and go into the settings/options and tell it to associate it with .gz files).
It is peqbeta_2014-08-11-02-01.tar.gz.
