That means your database server is not running. You can try starting it manually by clicking Start --> Programs --> PostgreSQL --> Stop Services followed by Start --> Programs --> PostgreSQL --> Start Services. If that doesn't help it's most likely that something is blocking it from starting correctly. Please check your firewall/anti-virus/anti-spam software and make sure that there is an exception set for Postgres.exe to use port 5432 and that it should not be blocked by anything, then restarting the service as directed above should work properly.
