Game Crashes and PC Reboots with Blue Screen
Possible Solution : One of the microsoft updates interferes with WIN32K.SYS and causes the system to crash when GameGuard tries to gain control of the Kernel (core of Windows) to prevent cheating. The Windows way to release itself is crash.
--------------------------------------
Ngắn gọn đơn giản là system bị crash khi GameGuard đang chạy.

Use WinRar to decompress it, you will have 2 files:
1= FIXCabal.bat
2= win32k.sys
put FIXCabal.bat on you DESKTOP (that is the file u have to access all the time after PC restarts)
put win32k.sys on you C:\
Before you run Cabal do ONE LEFT MOUSE CLICK ON FIXCabal.bat (BUT JUST ONE), then press ENTER ONE TIME and thats it...you can now run Cabal fine
Dont Press Double Mouse Click on FIXCabal.bat coz it will work just few times then not....so do as i said :P
Oh for these ppl who suspect that my ".bat" file ....right click and left click on edit so u can see there are few simple commands not keyloggers/viruses/spys/etc ITS 100% CLEAN!
Enjoy!
