Need Cubase 5 installer *CD not working - HELP*

Hello everybody. I’ve seen a post on this and tried replying there but had no luck. I wonder if a charitable spirit can point me to a download link to Cubase 5. Unfortunatelly my original CD is not longer readable (just found out) and since I reinstalled my whole PC, away went my Cubase. I’d be a shame to have to part with Steinberg after so many years, but since I live in a developing country and am only an occasional hobbyist, I’m not willing to lash out on a newer version.
Thanks in advance
