This is the method to get you to the configuration screen should you forget to provide a configuration button on one of your screens
When you first power up a Panelview plus a small white square appears for about 1 second, you need to push that point while the white button is present, it may take several restarts, another alternative is plug in a USB keyboard and push all 4 buttons together "CTRL & WINDOWS & ALT & DELETE"
Either option gets you to the configration screens, but now for the problem you could have, is that the origional developer has to have allowed the option of uploading the project, and this I believe is only an option in version 5 other wise the origional developer needs to supply you with a copy of the project, and a copy of the password.
