Downloading NIS

I've attempted to download the NIS purchased online X4. My account still says it is unactivated, and using Live Update it says 'expired'. When downloading the Norton symbol only appears breifly on the desktop. Sometimes with a small 'x' over it. This is a hassle and the fact you can't speak to a live person is a pain. Can you solve this problem or tell me how to get my $$ back? Glenn
