I had this problem when D2 launched for PC. None of my input devices work. On title screen the only button that works in the mouse left click which advances the title screen. I get to the character select screen and nothing works, I cannot move the pointer, cannot exit, keyboard not registering. nothing. This happened after the D2 servers were offline and recent patch updated. I've updated my graphics card (Nvidia). I patched and repaired after Termite bug. Now I can't play anymore.
