I am using AE CC 2014 (all up to date) on Windows 7. I have heaps of power including new GTX 980 Graphics card.
The problem seems to occur when I try to render after time re map. I have built a particle build up logo then done time remap to reverse animation.
The effect was created using Trapcode Particular. I have never tried this before.
Is this enough or what else would you need to know?
If you're not doing anything extreme with the Time Remapping, you might consider prerendering the particle precomp and see if that solves your problem.
Also, for the record, saying "up to date" isn't helpful. We've had folks say that when they were running 13.0.2.x despite the current version being 184.108.40.206
