Status_Code_Error
I am trying to update one of my apps but when I get asked to sign into the Mac App Store I get a "Status_Code_Error" appear in red letters to the bottom of the login window. I tried to email Apple Support but I get an Error 99 when using their support page. However, their Service Status page says everything is UP. Is anybody else having any similar issues in the UK right now?
MacBook Air, OS X Yosemite (10.10.2)
