Missing .ini File
 

So I just went to try and get my game into fullscreen to find I'm missing the eqclient.ini

This isn't hugely game breaking and I can play in windowed mode if need be, but if there is some solution, that would be great. Despite this file missing the game seems to run normally.

If eqclient.ini is missing, it is auto generated.

If your EQ folder is in Program Files, and the game is not run As Administrator, the file will be placed elsewhere (like in your User files or AppData files).

It's best to not have your EQ folder be in Program Files, but suit yourself. Make sure you run As Admin.
