I have also tried disabling the 2nd core of my dual core cpu by going to start menu, run, msconfig, boot.ini, advanced optoins, /numproc=1

I can play Everquest on another PC in my home network, an old single core computer, but still no luck on my original dual core PC.

I've also tried to get it to run on one core by making a shortcut to runfirst.exe with this as the target:
C:\Path to EQ\EverQuest\RunFirst.exe "eqgame.exe patchme".
Still same error. Any help is appreciated.
