When I started InDesign CS6 this morning I got a flash screen saying I have 28 days on a trial for a program I have owned for years,
is Adobe trying to drive me to Quark.
i had that happpend to me too. make sure your are sign in with the download app manager, there is a button that says register on that dialog box. click it and it will fix it, happens once in a while.
i do like the robot kill command on Quark, but you could not pay me to use it .
