This is a work computer and Reader is part of the supported install so I can't do anything with it. However, I do believe that it was recently updated (I remember it requested a computer reboot) and I'll bet that did have something to do with it.
If I uninstall and then reinstall ADE, will I have to reauthorize it? Or should I look at unauthorizing it before uninstalling it? Or should I just quit trying to buy books when I'm at work?
