To fix this problem you must
delete these files from your EverQuest Directory:
EQMain.dll
EQGfx_dx8.dll
EQClient.ini
EQGame.exe
EQHardware.ini
EQOptions1.opt
EQOptions2.opt
All files in the \Userdata folder
Any file with your Character's Name in it
The zone files your character is in.
I suggest this:
1) Make sure your motherboard drivers are up to date. This may be the most important update of all.
2) End task on all background programs and goto Trend Micro's Site and click on SCAN NOW and run a complete scan on your entire pc.
3) Windows Updates from
www.Microsoft.com
4) Reinstall DirectX
5) Reinstall your Video Card Driver
Do it like this
Download the directX 9.0b driver and save it. (do not install it).
Okay here goes:
1.) Uninstall the Nvidia driver.
2.) Restart your machine
3.) Uninstall DirectX driver.
4.) Restart your machine.
5.) Install the saved directX driver 9.0b
6.) Restart your machine.
7.) Install the Nvidia 44.03 driver
8.) Restart your machine.
9.) Try logging into EQ
It will work then, worked for me and a whole lotta other people.
