Help, why won't sonik synth 2 work in Fruity Loops 6?

[dreammaster777]

I have Fruity Loops 6 and I can open Sonik Synth 2 and Triangle 2 but there is no sound in the piano roll. It shows audio or a signal but there is no sound. My other Vsti's work fine in it, even triangle 1. Both Triangle 2 and Sonik Synth 2 work fine in fruity loops 4. Does anyone know if Sonik Synth 2 and Triangle 2 are compatible with Fruity Loops 6? If they are not than goodbye Fruity Loops 6.
