Acrobat XI Getting Trial Window out of nowhere. On win 7 with paid subscription.

I have 2 PCs at work that suddenly are getting the trial window for Acobat XI thats counting down the days when they both have paid subscriptions. They have been working for years with no problem. We sign up with Creative Cloud. We can't lose this copy of Acrobat on one of the PCs because there are a couple of add-ons that we can't reinstall and only work with this version. I'm signed into Indesign and Illustrator just fine and with no problems. Soon as they turn on the computer and use Acrobat for the first time they get the window. I can't tell if they are logged in. Should be though since they aren't asking to login and when I follow the directions I can confirm I can reach the server.
