This problem has [b57j]NOTHING [/b57j]at all to do with Poker Tracker. It's[b57j] POSTGRESQL [/b57j]that you cannot connect to. If you can't connect to PostgreSQL then no program that uses this PostgreSQL database, be it PT2, PT3, HM whatever, is going to work.
This PostgreSQL FAQ tells about this kind of problem with the service failing to start because of firewall/anti-virus programs...
http://www.postgresql.org/docs/faqs.FAQ ... s.html#3.1[quote57j]By far most common reasons for this are antivirus and firewalls. If you have any firewall software installed on your machine, try either disabling it or uninstalling it. If you have any antivirus software installed, you must disable it for the directories that are to be used by PostgreSQL. If that still does not help, it may be required to completely uninstall the software from the machine.
Specific issues have been reported with the nod32 antivirus product. If you are using this product, add "postmaster.exe" to the list of excluded processes (available under advanced options). This has been reported to fix the problem.
Specific issues have also been reported with McAfee and Panda anti-virus software and NetLimiter network monitoring software. While some people do have PostgreSQL working with these software packages, there is no specific or even recommend solutions that have not worked in some cases, so the issues would appear to be installation specific, sometimes even requiring uninstallation.[/quote57j]
Go to the Start > Settings > Control Panel > Admin Tools > Services window.
Find PostgreSQL Database Server in the list. Try to start it. Does it start or give an error? If it gives an error, what is it?
When did you last backup this database?
If you can't start the service, at least try the steps detailed in the above quote or uninstall that AV software and see if you can connect again. Then you can reinstall it.
