update Enfold crashed

Hi,

I try to update Enfold to the latest version, but I first get a blank page with the message: Tijdelijk niet beschikbaar vanwege gepland onderhoud. Probeer het over enkele minuten nog een keer. (Temporarily unavailable due to scheduled maintenance. Please try again in a few minutes again). After five minutes the frontend and backend returned, but with the standard theme Twenty-fourtheen, no Enfold, only the child-child I made. I re-uploaded my original version and could repare it. But now I have an outdated version of Enfold, en no update-message.
Could you provide me a clean most-updated version of Enfold? Or do you have a clue how to manage the problem otherwise?

Thanks in advance!

Martijn
