Adobe Creative Suite 4 installation files

[Ivan15A8]

Hi, I have to install my old CS4 for Mac on a macmini mid-2010. Unfortunately my old DVDs doens't work any more and my regular copy has not been registered in my account.

Where can I find the installation files for Mac OS-X?

Thanks

There is no download, no replacement. Maybe cleaning the DVD will help, but otherwise it is lost.
