Thanks for your replying.
I open the dbg.txt file and check the first line:
Starting EverQuest (Build Apr 17 2006 14:53:02)
so i think it's a Titanium version.
I didn't download any file from steam, I just moved(copy) whole everquest file from old pc to new pc

; from xp to win7
Does this cause the problem ? some settings have to be modified ?
Thanks.
