As very recently addressed here by GaryN (und others previously)…
“I guessing you're trying to download with a newer browser. The issue may be that the site is using TLS1 or 1.2 or some "obsolete" protocol and your browser won't negotiate with it. I was able to access it after enabling TLS 1 in Firefox 83. Firefox popped up a box where I could temporarily do that while warning me that choice will be soon be gone. How considerate…”SO... IF at first you’re unable to download files from this site,
you rather simply might try using a different browser.
Have had this problem before as I moved from Safari (11.1.2) to Google Chrome [87.0.4280.88 (x86_64)] as my daily browser of choice… on this Mid 2007 iMac running El Capitan. Just now I attempted the download of the M-Audio Transit software via Google Chrome and it was a
no-go. Then, simply opened trusty ol’ Safari and Viola! eZ-pZ download accomplished.
Problems? TRY ANOTHER BROWSER!
(Or deal with the TLS routine.)
Peace be with you.
