Shut down of game, due to abnormal gameplay

Every time I start MR, after I press the start button I wait for a few seconds and it shut downs and saying Security alert: Shut down of game due to abnormal game play code= 0xE090203... What do I do?

You run some program that is detected in MR for abnormal gameplay aka cheating, can be anything like DvdFab 5, Fraps, Teamspeak 3 Overlay and so on (ofc as well hack tools for MR ^__^)

I can't tell you which program it's causing but some program gets detected this way, I am sure.

Mugen, my buddy playing on MAC is having this issue. He games with us on PC using a copy of parallels and windows 7 (disturbingly enough this works great, despite the fact it freaks out if he even tries install something as simple as winrar on the PC emulation)
He keeps running into this issue on boot. Any suggestions? All he has open is skype on the mac and MR on the PC window.
