I was able to reproduce this issue internally to Eventide; it appears to be an issue with the way Safari (and/or Apple's login system, and/or WebKit, I'm not sure at the moment) handles log-ins to our website.
There is a workaround that I was able to use to allow correct access to the page:
-Log out of the Eventide website
-Log in to the Eventide website using the login bar at the top of the page (NOT the login link next to each inactive link)
-Re-enter the same URL in the navigation bar on Safari to force a full reload of the page.
On the reloaded page, the links should be available.
Please let me know how this works out. We will be working on fixing the underlying problem, but in the meantime this should allow access to the page.
