Schtserv Network

I'm trying to figure out how to connect with the server I guess...
I keep getting Error No903 the game tells me it cannot connect to patch server & To check SchtHack website for server details....Can ANYONE explain wtf is happening here??

Make sure you installed this version: https://upd.schtserv.com/SCHTSERV_PSOBB_Setup.exe

Also look for firewall or antivirus setting that could block the game

Error: You Don't have an account on this server.

I have tried using my account and password I have tried using my HL for pc Im not What username/password it is asking for and have tried them all. but this seems to be the error I always get a Tutorial on getting started with an account would be helpful.
