Render fails every single time at the same frame (HD res)

Hi!
I'm working on HD project (1920x1080). PC platform, AE CS3. My render fails at the end of the project (300 frames from end) on one specific frame - the one where a Videocopilot Twitch Effect (http://www.videocopilot.net/products/twitch/) becomes enabled. The weird thing is in some other places in the project Twitch effect is also used together with other memory-hungry effects and tons of layers beneth and above... and gains no trouble. Here, on the end of the project it is enabled in endtitles almost on single layer on black background! So there's no reason for AE to fail everytime this frame is rendered...
Help me please - I don't know what to do... This 300 frames left on the end of the project are like in prison :) And for not being guilty.
Is there any way to avoid AE rendering and use some outside software? I have tried Nucleo but it fails to.
Or maybe some codecs would do the trick. In Adobe Premiere I can choose which codec is used to render my stuff. Can I do that in AE?
Thanks in advance - micz

What else is happening on that problemmatic frame? Do any layers aapprear that weren't used before? They could be corrupted, they could be in a temporally-compressed codec(aka long-GOP or interframe compressed)like one of the HDV codecs, or just a stinkin' huge still. Any one of those could do it.
Does this ALSO happen at the same spot on RAM previews? If yes, constrict the work area, turn off any new footage, then turn it on piece by piece as you run previews to see what's giving you fits.

The layer above is the one which I suspect is the fun-killer, but the one beneth (don't be afraid - end stuff) is however in fact huge images sequence (4000x2500)... so maybe here we have a problem, like You said. I'll try to reduce the size. BUT I have a question - does it mean that AE simply CAN'T render compositions with huge objects? That should be mentioned in user's manual, shouldn't it?
And this is a screenshot of composition nested in the problematic one:
But I have discovered that it's not the guilty one - I have rendered it alone as a singular file PSD with alpha (there is no animation on this one) and placed it to the 03. gadzety dla tytusa composition and render fails so on. So it looks like source of the problem is "located" in 03. gadzety dla tytusa composition
And NO it's not happening when I'm using RAM preview

Not necessarily. There are things in the AE manual that just aren't true. For example: the manual says AE supports Open Gl, HDV video and mp3 audio. None of these things are true.
"And NO it's not happening when I'm using RAM preview"
I would check to make sure you have Open GL turned off for rendering. It is useless for any AE comp of any kind of complexity. If you have a lot of layers, you have complexity.

I have tried both about OpenGL - to turn it on and off, and there was no difference in case of render. It simply fails while rendering frame #6115. Is there any other solution? Maybe someone had troubles with Twitch and can help me here?

I don't know anything about Twitch. It still sounds to me like a corrupted file, or a common problem among newer AE users: using m2t, mp4, mpeg, mpeg2, h.264 or any other kind of compression used in HDV.
These kinds of files frequently don't work in AE, even though Adobe says they should.

I did some magical stressfull calculations and tried to "decompose" this whole project. Everything in this needed timeline period I rendered separetely - every subcomposition. Every. And I hunted down a bug I think. It was - like You mentioned fiew posts earlier - a very big piece of bitmap. It was something like 4000x5000 pix psd file containing only a small layer (abot 400x400 pix) on the middle. It was made by me to avoid situation when Twitch filer applied to a AE layer with this psd, reveal edges of that psd, when this AE layer is moved. I know it sounds weird - I'm sorry but my english skills seems insufficent here.
So - problem solved: too big file to handle by AE renderer... .. I supose... :)
Thanks for suggestions
