I'm running Win 7. I brought up CC to check for updates and saw I was signed out. I entered my username and password and ended up with the same message, which is below. I double-checked that I have the correct password by logging in here. I've tried multiple times with no luck. Any thoughts?
Nothing has changed with my antivirus or firewall.
