I tried to follow the tutorial for upload/download, and as you probably already guessed, it no worky.
The tutorial is for CS3 and above but in CC certain things have changed.
2. In the ID field enter 'upload'.
3. In the Label field enter 'Upload File'.
In CC there isnt an ID or Label entry in the property inspector, instead there is Name, Title, etc
Creating upload behavior
2. From the Trigger menu, choose Button: Submit pressed.
In CC the only option that had "submit" in it was, "Current Page Submit" (????)
Im not sure if these are where I went wrong but i cant seem to get it to work.
