Why do my drums and effects sound all high-pitched?

[MrKoekje Profile Website]

I was on FL Studio, finding the right sample to use for a gabber-type kick, but then suddenly, the sample I chose, as well as all my other drum samples and this one laser-zap noise sounded about an octave above what it should have been. What is the cause of this, and how do I solve this problem?

Think its the masterpitch. Just turn down the knob right beside the mastervolumeknob in the mainpainel (file, edit, channels etc) to 0 cents and it should sound normal again.
