If your support expired a freelancer form Envato Studio
hope your problem will solved.
This is what Kreisi support are saying: We’re sorry for the trouble, but this is out of our hands unfortunately, since there was a change in the Envato API/update procedure. The problem is fixed in 4.5, but the update to that needs to be done manually. You could try a plugin like this which should enable you to upload the zip file instead of updating via FTP: https://wordpress.org/plugins/update-theme-and-plugins-from-zip-file/
