Quick Message tab does not appear

Hi there,

I did a lot of research on this forum how to enable the Quick Message tab in CB for Uddeim but it doesn't work for me.

I have
- Uddeim installed (2.0)
- CB (1.
- Plugin Private Message System configured for Uddeim and published
- Quick Message tab published

But still does not work? Is there something else needed?
I checked out this documentation: www.joomlapolis.com/support/tutorials/111-picture-books/18269-uddeim-installation-and-cb-configuration-quick-start
and searched the forum and have no more clue what to do...

Please advise!

Best,
Constantin
