The SentryMBA can be found here. It was released in the BattleOn Games Hacks, Cheats & Trainers section, but it also works for League of Legends. As for the account scrapper, there isn't currently any working League of Legends account scrapper available on MPGH, unfortunately. I guess all you can do about it for now is hope that someone releases an updated account scrapper on it soon so you can download and use it along with the SentryMBA cracking program.
/Moved to the correct section, solved & closed.
