Resolution:
There are several changes in GridServer 5 license format that will affect customers. Most importantly, because GridServer 5 licenses now only need to be updated on the director, you will need a new license from the support or licensing (licenses@datasynapse.com) teams to run GridServer 5. (There are new fields like "broker count" that do not exist in the GridServer 4 license format.)

There are other changes to the hostname format:

    * Hostname wild card matching now matches on (sub)domains, so you will need to specify your (sub)domains if you have an unlimited license.
    * A port number must now be specified on the license.
    * Because the license is only loaded on the director, the initial release of GridServer 5 did not support port number wildcarding. Due to customer demand, this capability was added for unlimited license customers in GridServer 5 SP1 and later.
