I am trying to open a library epub book in ADE 4.5, which I just downloaded.  I keep getting the message: Error! Check Activation.  I uninstalled ADE 3.0 in case that was causing a conflict, tried uninstalling 4.5 and reinstalling, rebooting, erasing the authorization and reauthorizing, but nothing has worked.  It wouldn't let me erase the authorization.  I never used to have any problem with ADE 3.0.
