Server Error with Mac Calendar
I cannot open my calendar from my Mac because I get an error message that looks like the screenshot
I haven't been a subscriber to this calendar for two years and I'm not sure why it's causing problems now...but I cannot access the rest of my calendar because of this error, because it shuts down my calendar and I can never open it.
Help?
Thanks.
MacBook (13-inch Early 2009), Mac OS X (10.5.8)
