Boris Red 2.5 Will not update video on timeline

I am using the Boris Red-2 input-AVX 1.0 icon within my media composer. When I add that icon to the piece of video on my timeline, then go into the Boris plug in and move up and down on the timeline and the video does not update. I have tried the update image, refresh image, etc., nothing seems to work.
Deleted the Boris Preferences does not help.

Anyone have any suggestions?

Here are the specs on my system:

Avid Media Composer 10.1
Mac OS 9.2
Ram 1G
Boris Program Memory 400MB
Composer Memory 400MB
Boris Red 2.5 AVX Plug In 1.0

I have tried that as well, it does not work.

AVX 1.0 won't update video on Avid. You need the 1.5 plugin.

Hi all, whether your video will update in RED is entirely dependent on the AVX version you have installed. Avx 1.0 does not support updated preview , AVX 1.5 does. If you have Composer 10.6.1 (xpress 4.61) or higher, then you can install RED for AVX 1.5.....
I hope this clears up the mystery. This should also be in Release notes
thanks-
