Just a follow-up, I discovered where you can download the package files, but am still having trouble getting through the install process. I don't understand "you may upload manually" error. Can you guide me through that?
The process for importing a package is described here: http://ez.no/doc/ez_publish/technical_manual/4_0/features/packages/importing_packages_to_the_system
