Is the message prompting you to upgrade from LR6 to LRcc? Or from LR 6.0 to LR 6.1?
I have "X" out of it several times and don't recall exact language. But it is something on the order of *please upgrade Lr 6 cc....*
I tried the free trial of Lr 6 with never an intent to do the monthly. I purchased the Lr 6 DVD and have installed it. Not only is the nag annoying, but I fear that if I click to upgrade it will assume that I have the monthly subscription. I don't and won't. I just want a divorce - not a trial separation - from the creative cloud mess. I get the feeling that Adobe is trying to force the cc paradigm. It's only making me angry.
