I'm attempting to sign in to Visual Studio 2013 in order to take advantage of the cloud features (sync'd settings, etc.) but I get an error immediately when clicking "Sign In" anywhere in the UI:
If the image is not visible, the error is simply "Exception has been thrown by the target of an invocation."
I've tried this on various different days with the same result, so I'm sure it's not related to service status. Other devs in the same room have no issues signing in. I even went so far as to try adding *.visualstudio.com to my Trusted sites list.
Any fix for this?
