A couple of people who received private invites experience the following problem when they try and download:
"I was sent an invitation. When I click the link to download the program, I get sent to the main page of the site instead of downloading the program."
This problem seems to be associated with the recipient's firewall and how it handles URL redirections and referral stripping. We are making changes to our download script to alleviate the issue for the very small % of people who experience it. However if you have difficulty downloading from your private beta invite, please email support@eluma.com.
