Screen Resolution with new patch

[Kavious]

If you installed in Program Files, the client doesnt have permissions to write files there

In this case, all files (ini, screenshots, logs etc) will be written in AppData. Should be something like:
C:\Users\Name\AppData\Local\VirtualStore\Program Files\Sony\EverQuest

You will also need to select the View option to show hidden files to see the AppData folder
