Oh, I forgot to answer about project groups because I'm not sure what that means.  They are both under "books"

I only have one InteractBuilder account.  I did create the books on a laptop, then use dropbox to sync the files with another computer, so they were loaded into the program on the desktop computer by way of appearing as folders in the home folder for books.  I did duplicate app A long after having uploaded it to InteractPlayer.

Hi Eleisha, I am accessing my app on two computers using dropbox.  I just set the default folder to the same folder in dropbox on both computers.
