This has been posted a few times, and has been addressed to some extent. the fix is of course to rename your nektulos.eqg file in your client directory to nektulos.eqg.bak
Having said that, I made a batch file to do this automatically if you want to distribute this to your users, feel free to do so, and if you are afraid of what it does, right-click and click edit, and you will see what commands it performs.
This is what you will see in the file:
@echo off
(This makes it so the cmd prompt doesn't display everything it is doing up on the screen)
cd..
cd..
cd..
cd..
cd..
cd..
cd..
cd..
(This changes directory to parent directory a bunch of times, the goal being to get you into C:\ )
cd progra~1
(Changes directory to C:\Program Files (DOS can only handle 8 characters))
cd Sony
cd Everquest
(changes directory to your everquest client folder)
ren nektulos.eqg nektulos.eqg.bak
(changes the filename from nektulos.eqg to nektulos.eqg.bak)
Then it pauses, wanting you to hit any key to exit the program.
So, here is the batch file, compressed using winrar.

Hope this helps some people. Don't forget to run this batch file on the same hard drive you installed Everquest.
