PokerTracker

I have not been using PT4 for a long time and when I upgraded to the latest version I can't get the databases to update so I can't use PT4 at all and I seem to have lost all the information I had.

What version of PostgreSQL do you have installed and how large are your databases? In the meantime you can try creating a new database and that may allow you import new hands and use PokerTracker 4 on your tables:

Guide: Creating A New Database in PokerTracker 4

It is version 8.4.22 and it does not let me create a new database, I get the error of the image.

This error only happens with very old PostgreSQL versions such as v8.4 which reached its end-of-life in 2014 and is below the minimum required version for PokerTracker 4. To fix the issue you will need to install and use a newer PostgreSQL version and then restore your database provided you created the recommended backup - see this guide:
