"Corrupted Memory #X: BattlEye detects that your game's memory is not what it is supposed to be. Scan your system for viruses/trojans/spyware and check your RAM for possible defects (using tools like Memtest86). If that doesn't help, the game's installation on your harddisk is possibly corrupted - therefore, try to reinstall the game."
