BSplayer won't open. "active system debugger"

[coolname]

I've downloaded the newest version, the debug version, all kinds of different versions, but every time I try to open it, it says "This program does not run on machines with active system debugger!"....and I had no idea that I even had an active system debugger....I don't even know what one is. I closed all applications running and it still does the same thing. help?
