just to recap, you are following the steps in the guide exactly
http://www.eqemulator.net/wiki/wikka.php?wakka=GetTit, you did:
Step 3 - Changing the EQHost file
Click 'Start', go to 'Run', type in, 'C:\Program Files\Sony\Everquest\eqhost.txt'
Modify the file to look like
[LoginServer]
Host=eqemulator.net:5998
Save and close.
and then:
Step 4 - Creating the Shortcut
I'm assuming you know how to make a shortcut on the desktop.
Make a new shortcut, I recommend you do it on the desktop, but where ever you want is fine.
The Target should be '"C:\Program Files\Sony\EverQuest\eqgame.exe" patchme'
That is it for getting on, now you need a login server account.
