Download Previous Cubase Version Updates OSX

I have a piece of software that works with Cubase that I want to use. The problem is that it currently only works on version 8.0.10 not 8.0.20. I have gone back to my original install file but that installed 8.0.0. Is there somewhere that I can download the 8.0.10 update file. I cannot find a section anywhere on the website for downloading older versions.
I am running MAC OSX, so doing the simple uninstall trick on Windows is not possible.

Problem solved. I contacted my local Steinberg Support Distributor and they sent the file within a day. Great service thanks.
