So far I've noticed when I go to run the game by clicking the shortcut an error pops ups saying PVP.net Patcher Kernel has stopped working. I've corrected this problem by right clicking and running in administrator mode, but the client log in screen never shows up.
As others have previously stated, there is just a blank screen with no log in information. I've tried going into the properties, but when clicking on general tab the game states that I need to verify the location is correct and it will not save the setting run as administrator. I've attached a picture of what the log in screen looks like although it's just a blank screen.
