Everquest 2 has detected an unrecoverable error

Hi Brainy,
I love to play games in the computer, so I installed EverQuest II. I am getting a weird error when I play EverQuest. The error sounds like missing some files in the computer. I tried the common methods uninstall and reinstall but nothing seems to work. Do I need to download the DirectX? Please suggest me some solutions to solve this error. Thanks in advance.

EverQuest II has detected an unrecoverable error and must shutdown.
