"Sorry, there are no available sessions"

Hi guys,
Having purchased the coloured user manual I believe that we have set everything up per the instructions. However I get the following error message when an agent logs in:
"Sorry, there are no available sessions "
We have searched this forum and tried all the ideas presented, but still no luck.
Andy ideas?
Thanks
Andy
