Menu- tools - Manager - you'll see list of all your applications- scroll to the application - press the middle button i.e the one rounded by navigation button(up,down,left, right) - select suite settings - edit user data - always allowed - press back and launch ur application. Download and upload as you wish. It's already enabled on Eseries.
