Black Screen of Death?

[Quanefel]

I was just in Lamannia and used the "Reset Default Setting's" button in Options panel and now BOTH my clients will not display anything. The screen is black the moment I log into each now, what is going on? How can a glaring bug like this been overlooked? Am I forced to reinstall both my original game and Lamannia again, and if I do....will it even reset things so I can actually use them?

*Edit* I uninstalled and started the reinstall of Lamannia but....get to character selection screen and STILL have a black screen of death. Nothing changed.
