Hey Wagner -
Send me a few screen shots, so I know we are on the same page. If you are logged in to the Hub with an ID that has the ContentAdmin Role (or even a newly created ID) you should be able to create Apps in the My Work Stream, not in any other stream. (A ContentAdmin - can publish Apps to those "other" streams from the QMC).
Let Me know, I'll send you some sample screens of mine when I get to my machine.
