The request for account “iCloud” failed. The server responded with “400” to operation CalDAVAddSubscriptionCalendarQueueableOperation

Does anyone know how to fix this problem? Or even what the problem is? I am trying to subscribe to a calendar and every time I do, it gives me this response:


The request for account “iCloud” failed.


The server responded with

“400”

to operation CalDAVAddSubscriptionCalendarQueueableOperation


Any help would be fantastic. This is a course calendar, and I really need it.


Thank you!

PowerBook G4 (15-inch 1.67/1.5 GHz), OS X Mountain Lion (10.8.5), iCal
