I bought the complete package for annual students a few months ago and I also downloaded Ai, Ps, Dw, Id; Fl etc ...
unfortunately I would also Ae (After effect) and when I go on creative cloud I do not show precisely, instead if I go on the site makes me see the download button but after I clicked tells me that at the moment you can not download, and so I have to ask for assistance adobe. You know why I can not download it?
