so when i try to run PT4 i get this message:
"Unable to login to database (postgres). Reason: could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "???" and accepting TCP/IP connections on port 5432? "
After clicking configure defaults i get the connect to postgreSQL Server ... i click "connect" and then i get "Unable to connect to this database. Please check the configuration."
what to do ?
