thank you for your help.
I tried to do this again. Everything was looking fine. I installed PostgrSQL 12.17.1 - there was no 12 without extension.
Than a "Stack Builder" Programm opened and I was looking inside - it says, that PostgresSQL 12 is already installed. It didn´t ask me for any password.
So i reinstalled PT4. Thist time it was quick an opened like it should do.
BUT: After importing some handy from GG the same problem began: I opened a Hand, where I was dealt AA and when I clicked in the hand or in the replayer it showed me a completely different hand from an other player with A4.
PT4 didn´t ask for my registration code and already had my PS Player Name inside.
So still something is very wrong.
How can I uninstall definilty everything from PT4 - that there is nothing left?
I don´t know, where this problem is.
As I was installing it first - everything went fine till I started to import data from an other tracker.
Isn´t it possible to get back to "preinstallation" and start everything from the beginning?
I had contacted the PT Support already, but there is no response from them till now....
I really don´t know what to do....I am no programmer....just want to use the software... ??
Please help me
