I have a core (810) and one MD up and running but when I try to download the mobile orbitter for my laptop or mobile phone the install files all return 0 bytes. I checked on the core and the are listed in the /usr/pluto/installers but there they are also 0 bytes. I had a lot of work to get the core and md running so I don't want to install the core again. I looked on the DVD but can't find the files there. How can I get the correct installers again?
