M14 secondhand - no CD

I bought a Steinberg recently on eBay only to discover the seller didn’t include the CD with it and won’t respond to my messages about it. I’ve raised an issue with eBay about it but is there anything I can do in the meantime without his cooperation and without the CD?

The other issue is that like another poster, I have Windows 8 64 bit and don’t see a driver listed for this.
