I'm currently researching a similar issue here:
http://boards.cityofheroes.com/showthread.php?t=234320
Manga @ Triumph
"Meanwhile In The Halls Of Titan"...Titan Network Working To Save City Of Heroes
Save Paragon City! Efforts Coordination
I need a better fix for the Black Screen issue. Since the last patch, I have to delete my COH Preferences folder, start in safe mode, switch my graphics settings, quit and restart the game, Every Time I Start The Game. Every. Single. Time.
I'm on the verge of uninstalling.
Help!
