also it seems like you might be having issues with administrator privileges, considering that you cant save your UI. what is the path to your EQ install, and are you running the game as admin?
if you have uninstalled software from your PC recently, or if you have alot of background processes running, any of this could be causing your issue.
again, i would recommend a fresh OS install, but that might be a drastic solution to a simple problem. anything you have installed that is not part of windows could potentially be causing the problem.
