PokerTracker

Previously had a fully functioning database. Another program accidentally screwed up my previous setup. Removed all software/files relating to pokertracker/postgre. Did a fresh install of both and now will attempting to setup PT4 I get the following message
"Unable to create PostgreSQL database: PT4 DB
Reason: Unable to login to database (template1). Reason: FATAL: could not open relation mapping file "global/pg_filenode.map": No such file or directory"

Help!

Please follow this tutorial and then manually download and install PostgreSQL 9.6 available from here. Using a Mac administrator account or administrative privileges install that PostgreSQL and for the password boxes use "dbpass" (no quotes) which is what PokerTracker 4 uses by default. Once PostgreSQL installs successfully reboot your computer and then try again.
