MisFire - Frames won't render.

Hey There, I am in desperate need of help.
I have made a motion graphics video, everything made INSIDE of AE, project at 720p and 25fps.
Here is the problem: When I do a preview (at 1/4, 1/2, anything), the preview stops at a dead frame. I tried previewing each frame individually so that I could see where the dead frames are and how many there are. When I render the composition, the render fails at the first dead frame. I've tried disabling the misfire effect, it worked. So it's obviously MisFire that's causing this problem.
Does anybody know how to resolve this problem? I've tried the secret prefs, didn't work.
I have a 4GB ram on my PC, AE uses just under 3GB. I use multiprocessing, 2 frames at a time.

Thanks for reading, please help me out! :/
