Q: Transfer Logic Express from my old MacBookPro

Hello! I got Logic Express (physical version / CD) and installed it on my old MacBook Pro with CD / DVD player. Now I have a new MacBook Pro Retina and want to download the Logic Express to it. I would like to know how to proceed because I didn't find in the "Purchased" section of my Apple ID.

Thank you!

P.S. Sorry my poor English
