I can create a Bannerzest file with the images I want, quit bannerzest, and reopen it and all the media is gone. It also won't save the server information and if I try to upload to the server it crashes. The media I've been using is just saved on my desktop and I haven't moved it. I have BZ Version 4.0.3 (5896) and El Capitan 10.11.2.
