License server cannot be reached / 1/21/11

Joomla! 1.5.15 Stable [ Wojmamni Ama Mamni ] 05-November-2009 04:00 GMT. We are getting the license server cannot be reached in Community Builder. At this point we do not even see the subscription tab at all.

This is for the last two days (today is 1/21/11)
Under Community Builder/User management and clicking on any user under subscription we get the License server cannot be reached and as noted, I get nothing under the subscription tabs.

We have changed nothing, is your license server down? Our hosting company (so far) is saying that they haven't changed their firewall.
