This issue has been fixed via PM, a simple restart was necessary on one of the client's servers.
Confirmed, there was a timing issue with our license regeneration during the recovery that affected a very small number of clients -- if anyone is experiencing licensing problems, simply run:
/etc/init.d/centovacast restart
On the off chance that you still have a licensing problem after restarting, please immediately PM your actual license key (in /usr/local/centovacast/etc/license.conf) to centovasupport here on the forums and we will investigate immediately.
The very reason why it's taking so long to get the secure server back up is because we're trying to eliminate ANY possibility of licensing interruption when it comes back up, so any licensing issues happening NOW are of course our top priority.
