Boris AEX plug ins

Hi
Avid Media Composer Adrenaline 2.8, HP XW8400, 3Gb RAM, 1.2 Tb 4 way striped SAS drives, additonnal SCSI and SATA drives. Avid FX 5.7
I have a problem with chroma keying in Boris RED. (also knowsn as AvidFX). I would like to have access to more settings than the (very) basic "resident" Boris Chroma Keyer.
We do a compositing using around 4 stills, and up to 5 videos. All elements in a "container" I of the videos is choma keyed. I have however edges issues. These issues can be solved using a plug in such as DFT Zmatte, This is an AVX plug in, but also exists as AEX (After Effects FX) plug in, in theory, Boris RED compatible. But when I apply this FX, Boris crashes, (and Avid too) I tried Primatte keyer, which has the same behavior.
I also made the Boris "engine" test standalone software, which has the same reaction. (crash)
Here is my question, what Chroma keyer AEX plug in (except Boris) will be Boris RED compatible.
Just for info, other Avid users trying to help me, suggest I use an additionnal Avid Chroma keyer, this is NOT possible here, I must do the whole work INSIDE Boris. and then render, I can't cumulate an AVX (Avid) chroma key FX and a Boris FX on a same clip on the Avid timeline.
I hope this question is clear enough.
Many thanks for help.
