[cvsnt] Websphere 5.1.2 - newer cvsnt does not support

[Shripad Kanaskar]

Hello,
I am not sure whether this is the right place to raise WEBSPHERE question.
I am new to this user group.
I am using websphere development studio V5.1.2
This version does not support newer CVSNT version 2.0..
It does support (CVSNT) 1.11.1.3  (Build 57i) .
This is an older version and could not find any download site.
Could you help me?
Thanks
Shri
