Just purchased license, can't register server

• Vembu-VMBackup

I just purchased some licenses for our server however when i try to register the server I am unable to do so.

The popup appears asking for my Vembu portal account, so i entered the email address and password but when i press the "register this trial" button nothing happens.

It doesn't appear as though the form is being submitted for authentication and there is no "loading" animation and nothing loads.

I have tried this on several machines and web browsers, even from the backup server itself.

Any idea how I can register this server?

Thanks,
