This has happened me before and i've had to start a new databse but i've hands on 300k players and there's no way i'm doing it again.
The only thing i did different today was to download Microsoft Security Essentials and Malwarebytes to check for virus, and HEM stopped working. Is it related?
The option to connect to PostgresSQL is Server 127.0.0.1 and Port 5433
Any ideas?
