Calendar Importing

Hello,

I hope all is well, and write with what I hope to be a quick question.  In attempting to manually import both the Divinity & Judaic Studies calendars (via religiousstudies.yale.edu/import) to the Religious Studies calendar, I receive the following error message:

“Download of http://calendar.yale.edu/feeds/feed/divinity/json-list/today/3months failed with code 404.”
“Download of http://calendar.yale.edu/feeds/feed/judaicstudies/json-list/today/3months failed with code 404.”

Might you know what the problem is, and how to fix it?

Kind thanks!
Heather
