I've just installed HEM on a brand new clean empty computer. I ran the holdem manager installation exe and clicked next a bunch of times, and postgresql was automatically installed in the process. The version it installed was outdated, 8.1 or something, while the most recent one is 8.4 or so and has had some security fixes since, which I find important. I've downloaded the 8.4 installer, which says it detected an older installation (8.1), and will upgrade the existing installation instead of installing a completely new one. Then it asks for the "password for the database superuser and service account (postgres)."
I never specified any password during the installation of holdem manager, and the passwords your FAQ suggests also don't work. Holdem manager is working fine. Help?
