Configuration : JOOMLA 1.6, CB 1.4, CB Subs, CBSubs Fields Tabs Protect

I can't figure out how to display specific tabs to specific usergroups. Let me please explain you my problem :

I have created 3 new registred usergroups in Joomla backend: individual, company and ngo.

I have created 3 differents contact tabs in CB Tab Manager : Contact (I) for individuals (User Group to allow access to: individual), Contact (C) for companies (User Group to allow access to: company) and Contact (N) for ngos (User Group to allow access to: ngo). The tabs are published.

I have created a specific menu item with comprofiler


After login each user is routed on is specific "privat area". Each groups have specific horizontal and vertical menus and articles etc. and all this work fine.

But no "Contact" tab appears in the Profil tab.

Could someone help me to solve this problem,

Thank you in advance,

Cheers

Bill
