Q: Keychain / Account Access with Maverick (OSX) not working

- It began with issues logging in to FaceTime and iMessaging... after following a bunch of discussions, I ended up resetting my keychain (https://discussions.apple.com/thread/4654777?tstart=0 and https://discussions.apple.com/message/22769001#22769001). Now, when I try to log in to iCloud, the Sign In screen just cycled... and cycled.... and cycled... and then just gave up. No error message, no warning, simply reverts back to the blank Sign In form as though I have not done anything at all. So I signed out. Now, when I try to sign in with a fresh start, it cycles for about 4-5 minutes, and tells me that I just can't sign in at this time.

I've checked the iCloud systems status (http://www.apple.com/support/systemstatus/) and made sure everything was online. I can sign in to the website and to my Apple Id as per normal (even changed passwords just to make sure), but nothing on my actual computer that requires an apple ID seems to be working... also I've noticed that App Store seems to be stalled on login as well, the window won't even pop up. I've noticed that prior to today, there seemed to be a lot of dodginess with logging in to icloud and app store (since I've upgraded to Maverick), but today is the first day it just quit. Needless to say, I'm very frustrated and in need of some help!
