Greetings,
First things first, you have to know what version of everquest you have before you go randomly trying tutorials out

. This will just save you weeding through errors that are caused to a weird patch issue. So what I recommend is to search the forums for a program called EQ version check, run it as per the i nstructions it has w/ it, and it will tell you which version of the EMU to use w/ your version.. At that point, you need to just search in the tutorials forums, for setting up a server w/ the version the version check told you to use !
Also , bad news, if you've j ust recently played live EQ .. you probably don't have a playable version and will just have to wait for a further release that works with your version of everquest.. What i suggest doing now is at least backing up your current eq directory for future use w/ the emulator !! good luck and any more questions i'll try to help.. except that i'm very new as well .
kindest regards,
