I just downloaded CS6 Design Standard and when I started Indesign I got an error "Cannot load assignment UI.IndesignPlugin because in requires Username. Please install the Username plug-in and restart inDesign". There is no user name pluigin in the plugin folder and the UI folder is empty.
I installed it twice. Do you think I need to download the entire CS6 package again?
