So you installed the game (5 Disks if Titanium) which is the only client supported anymore.
You downloaded
http://www.project1999.org/files/eqchangesv18.zip and replaced the files in your EQ directory.
Did you follow the setup procedure at
EqEmulator.Org
Did you change the files needed to by EQEMU? Specifically the EQHost file?
Step 4 - EQHost File
In order for your client to connect to the EQEmulator Login Server (and not SOE's EQLive Login Server), you will need to change your eqhost.txt file to point at the correct location. Go into your EverQuest directory and locate the eqhost.txt file. Replace the contents of the file with the following (Remove any trailing spaces):
[LoginServer]
Host=eqemulator.net:5998
Step 5 - Creating Shortcut
Now, you will need to create a shortcut to launch EverQuest and bypass the EQLive patcher (if this step is not taken, you will launch the patcher and overwrite the EQHost.txt file that you just modified, making you connect to the global EQLive Login Server). To do this, go into your EverQuest directory. Locate the EQGAME.EXE file. Right-click on the file and select "Create Shortcut." You can rename this shortcut and drag it anywhere you'd like (most people like to put it on their desktop). Now, right-click that shortcut and select Properties. In the target box, you will see the path to the eqgame.exe file. We need to edit this so that it will pass an argument to that executable when the shortcut is launched. At the end of the text box (after any parentheses), add "patchme" (no quotes). Your target box should look similar to this:
"C:\Program Files\Everquest\eqgame.exe" patchme
Or if you do not have spaces in the path, it will look like this without quotes:
C:\Everquest\eqgame.exe patchme
Let me know if this helps, I'd be willing to help out further if needed, but I won't be back at a computer for another hour or so.
