Why don't the hqx files download on Ubuntu

I posted elsewhere and am new to this forum and wanting to finish this task. I am trying to download the updates for Cubase VST 24 Mac Os9.2.2 so I can use the s/w that i paid for and still want to use. (I also paid for and own Cubase 6.5 but actually prefer the older version.) I am creating a back-up set up on a G4 I just got before the one I am using becomes an r.i.p. I access the internet via a Linux Ubuntu laptop and would like to simply download the file I need and install the update on the mac in question, which DOES NOT have internet access. Why is it that I can’t download the hqx file in question???
