Go to this folder:
C:\Program Files\PostgreSQL\x.y\data\
where x.y is your PostgreSQL version although you may have it installed in another location. Delete the 'postmaster.pid' file inside that folder (not 'postmaster.opts' which may be there too), reboot your computer and try starting PokerTracker 4 again. If that does fix it then click your Windows Start button then type the following command:
services.msc
and click on it when it appears. Do you see the PostgreSQL service in the list? Is it started, or can you start it? What is its 'Status' and 'Startup Type'? If the PostgreSQL service is listed but not starting then open the Event Viewer (in the same way - if you type 'event' you should see it). In the top left section, expand "Windows Logs" and click on "Application". Do you see any recent errors in the top center section for PostgreSQL? If you do let us know what they say.
