Problem with extensions OpenVox UC300

Hello! Please, help
I have a OpenVox UC300-AEM2 and when i created 60 extensions and reload device, my openvox loaded with warning :

ERROR: Failed to find License file

Licenses UID: a098050205bb
Upload Licenses
Warnning: Device will reboot after license file uploaded
One license corresponds to one IP extension, UC300 Series can support up to 800 extension registers. The factory default IP phone registers of UC300 Series are 30, if you want to enhance your communication system to meet your needs, please buy the extra license. The license price varies from 8 to unlimited.

What I can do ? In the past when I set up the device, it wasn't and I was allowed to create more extensions than 30.
But now this is happened when i dowload last fireware from your website.
Please, help me.
