As said in the downloads section, you must TURN OFF YOUR ANTIVIRUS to avoid errors. If you missed that part, your launcher file will be deleted/blocked by your antivirus because of a false virus alert due to the game guard.
Lesson learned, turn off your antivirus before extracting this file:
I have the same prob too I've already added the Launcher.exe to the exceptions. After I click "run.exe" the launcher still won't appear.
Check in the task manager if the bandmaster.bin is running in the process.. if it is, change your screen resolution to either lower or higher.. trial and error. According to google, this kind of problem has something to do with our PC's screen resolution so check your resolution, check your firewall if it's not blocked, disable your antivirus coz I had mine in exceptions but it gets deleted sometimes. Otherwise, try to check your PC status if it's updated especially your driver or video card.
