There are two ways to attach full text in EndNote.
The first time you look for full text in a session (everytime you start EndNote), it should open a window that asks you to sign in. When you sign in using your JCU username (jc######) and password, it will go through to your User Profile (this is your security user profile for JCU). This means you've successfully signed in, so hit "Continue" at the bottom of that window (in the EndNote part of the window, not the User Profile). Authentication does time out, so you will need to authenticate again at some point.
This video contains instructions on finding and attaching PDF articles and how to annotate PDF articles within EndNote.
Instructions on annotating PDFs start at 18:30 mins.
