iCal error message after iOS 8 update

[BuddyAir]

Hi All,
After updating to iOS8 & turning on family sharing, my iCal is giving this error continually on both my MacBook Air and my iMac:
"The server responded with an error.
Access to account “iCloud” is not permitted.

The server responded:
“403”
to operation CalDAVAccountRefreshQueueableOperation."
It then gives two options, "Try Again" or "OK"

No matter which one I hit, it waits about 30 seconds and says Updating and then the box pops up again. iCal appears to be working on my iPhone. We tried turning off family sharing and the problem still persists. Everything is updated & running OSX on both machines.
Any thoughts would be appreciated. Let me know if you need more info.
Thanks!

My wife has this problem as well on her iMac. I've searched repeatedly for a solution...completing removing iCloud from every device she has and then logging in again has not fixed anything. Would be grateful for help if anyone has solved this.

It's been "calendar" not "iCal" for a few years now lol

Also, upgrade to Yosemite and see if that fixes it.
