I would double check that your resolution in your eqclient.ini file matches what your monitor can handle or less. Or what Samoht said. jk.

If this is the issue where your windowed and click out and window out then crash when you try to full screen it. The only fix I have found is to go into ALT+O options and go to screen resolution, select it even if it is already what you want it at and confirm. Or you can use WinEQ thats what i eventually did to stop it.
