Preview Screen messing up.

[random]

I was following the Speed Particles Tutorial, and everything was fine up until i typed in that long code so particles are only realsed when the text reaches a certain speed. After i did that i tryed previewing it but my preview window keeps showing weird colours and textures when i play it, like my graphics are messing up. It's happened on my 2 attemps that ive tryed it. I'm quite new to after effects and i have 7.0. Is this just my computer or do you think it could be something im doing wrong?
