Jazz,
When you don’t have access to the UI the way to uninstall the Secure Delivery Hub will be to manually delete the Delivery Hub directories, look at your install unattended file and delete just delete the directories you used to the following properties:
server.dir=
server.data.dir=
My guess is that you’ll need root access to delete these directories, once you’ve done this you can simply re-run the installer and you’ll get a clean Delivery Hub Install.
Best Regards
