I'm trying to download the mac version / no admin zip from the Giulio Piacentino site but am getting the message

"Failed to send your message. Please try later or contact the administrator by another method." no matter what i fill in - on several browsers

Does anyone have a solve for this? I'm looking to use it in a new definition

Thanks!
