iCloud.com calendar is locked
Hi
We have a number of iPhones and PC's that use iCloud for contacts and .
Yesterday we had to restore our calendars via the iCloud.com backup system which let you roll back up to 30days.
After the restore completed the calendar isn't working on any of the PC's, iPhones. When you try re-enabling the calendar in the iCloud software on the PC you get the following error. "Your setup couldn't be started because the iCloud server stopped responding" This is the same for all PC's
Also when you log into the icloud.com and click on calendar web app you get "Calendar is Locked. Due to Account maintenance, calendar is currently unavailable"
I've check the apple's service status and everything seems to be online.
Can anyone help.
