Could not load iCloud Accounts preference pane
Hi,
I have a 2011 MacBook Pro running 10.10.2. All of a sudden my Messages won't open and I can't log into my iCloud account from the preferences. When I try I get the following error message.
"Preferences Error. Could not load iCloud Accounts preference pane"
Any guidance on resolving the issues is greatly appreciated.
God Bless!
MacBook Pro (13-inch Late 2011), OS X Yosemite (10.10.2)
