Guitar Rig 2 crackling sound

[Messizzle]

Hey
I have Guitar Rig 2, but when I use it I get these little crackling noizes all over my beat. It almost sounds like I'm playing a scratched vinyl record. It's not the CPU, 'cause I have 2GB RAM and a dual-core processor so that should be enough....? Anyone that knows what could be wrong???

BTW, I use it through FLStudio7

Thanks.

is it a crack version? when I didn't register mine, it would put this white noise fuzz every so often throughout the beat...
