cannot add icloud public calendar to outlook

I work and live in a mixed Mac/PC environment. The PCs are Windows 7 professional with Outlook 2010. The Macs are Yosemite. I would like to be able to subscribe to a public icloud calendar on one of the PCs. We could do this a week ago.

Now when we add the calendar it crashes Outlook. Furthermore, I noticed that the calendar address no longer ends in .ics which Outlook requires.

The new icloud control panel crashed Outlook as well.

I tried joining the private calendar and it does not show up in Outlook either.

Is the new icloud interface not ready for prime time?

Any solutions or work arounds?

Thank you in advance for any help,

Debbie
