What I submitted as ticket to k2 [even though it says its an MGame corp problem]
Title: Blue Screen On Exit, Problem Caused By Knight Online MGame
Description: Each time I try to open Power-Up Store or exit the game without using Windows Task Manager, my computer restarts, and goes to a Bluescreen containing data saying, crash dump. After the PC is restarted, Windows Vista says; "This problem was caused by Knight Online (XDva009.SYS). This program was created by MGame Corp.. MGame Corp. does not currently have a solution for the problem that you reported." Then the Vista message directs me to ask MGame for more assistance. Maybe you guys have some bug you need to upload to Vista users?
