CMC FD not recognized in NUENDO4 with CC121

I dont know if that CMC FD do not be recognized in NUENDO 4 (with last updated) or is a problem that I have the CC121 working on it? Any knowledge about it?
My Nuendo is working over Windows XP.

According to this:
CMC Compatibility Chart

I don’t believe that the CMC’s are compatible with Nuendo 4
