CCS 5.1: No update for cgtools C2000 6.1.0


I am running CCS 5.1 with valid subscription and do not get the update on c2000 cgtools 6.1.0.

From, it should be available since 2012-03-21.

My setup only shows cgtools 6.0.2 (Window/preferences/Code composer Studio/Build/Compilers).

The "available software sites" includes ""

Where/how can I get cgtools 6.1.0?
