Hello,
I want help with halion 4 in my imac,
what can i do with this message:
A communication problem occurred while accessing the license server. please try again after dawonloading and installing the latest version of the eLicenser Control software from (http://www.eLicenser.net) , or contact your software vendor’s support department in case the problem persists

my License Control Center (6.3.5.6090).

Do what it says and try again later?

Server could be:

Your internet is at fault.

Checked: It is the latest e-licenser version.
