Hey Ghostwriter, you can shut it off (or change the frequency of launch) within the "preferences"
just go to the EDIT (1) then down to PREFERENCES (2) scroll all the way to the bottom and select the ADOBE ONLINE option (3) and a dialog window will pop-up letting choose from the drop-down menu (4). You can choose One Month, One Week, Every Day or (my favorite) **Never**.
hope it helps,
:)
