Could you send the serial number to me at communityhelp@aerohive.com, along with a sales order from Aerohive or proof of purchase if you purchased from someone other than Aerohive?
You would need to purchase either partner or select support to get access to our downloads section in Hive Community. We do have a free HiveManager version available that will come with the latest firmware, this guide will walk you through how to register for that if you're interested: https://thehivecommunity.aerohive.com/s/article/Registering-for-HiveManager-Connect
