I recently renewed my Eset endpoint protection standard , i received an email with one attachment EAV-xxxxxx.lic file , a license key wich i got from the convert site, a public ID, user and password. My structure have an Eset Remote Administrator ver 5 and several endpoints. Currently my ERA ver5 server have a expired license and when trying to add the new EAV-xxx.lic file i get a error code 20086 expired key. The license is new and isnt used. How can i activate the ERA ver5 server.
