Cineware not translating emitters properly?

In After Effects, using Cineware, the particles from my emitters aren't properly making it in to After Effects.

For example, here's frame 40 in Cinema 4D:

Now, here's that same frame in After Effects:

Both the C4D and AE files are using the same frame rate (24). And if I keep playing the AE timeline, it does add more particles, but nowhere near like it is in the actual C4D file.

So...I'm stumped.

For reference, I'm running Cinema 4D Studio R14 and AE CC.
