Hacking Prevention Tool Has Ended

After the June 12 maintenance i loaded gamelauncher, pressed "Game Start". It loaded normally until it gets to the load screen before login screen, when a box pops up saying "Hacking Prevention Tool Has Ended" and then seal closes.

please help thanks

Notice:

i have 2 laptops and this "Hacking Tool Has Ended" box only happens to one of my laptops.

Edit:
re-installation/download did not work... -_-
someone please.... any help would be appreciated

same thing happens to me.. it has been going on everyday since that patch
