Installing bought CrossDJ on new MBP Retina

Hi all,
This may be a very stupid question but I haven't been able to find an answer elsewhere.
I have just bought a new MBP Retina (with no CD drive) and wish to install crossDJ (I have 2 CDs that came with my U-Mix Control Pro).
Is it possible to use my CD Keys from my purchased software at all to get my purchased full version on my new laptop?
Any help is greatly appreciated.
Thanks!
