Update Santino 2.3 to 2.5

Please help me upgrade Santino 2.3 to 2.5 version. I hoped, but can’t automatic upgrade with Envato Toolskit plugin.
Generated API code, but in Envato toolkit show - User not found. This can sometimes occur if the user has registered with
https://account.envato.com but not logged in to the marketplace yet.

You can try to update the theme manually or I could offer a custom job if you’d like me to fix the problem quickly.
