Every time I download an upgrade to the luna software, it always seems to want me to insert an installation disk which I've never had with the product? Anyone else come across this problem?

Probably the files you downloaded (or just one of them) didn't download in full. If the installer asks you to insert, say, disk 4 - it may mean you should try to download the 4th part of installer once more.
