can I retrieve my Cubase program from a computer that crashe

My laptop got wet and had to be replaced, I have what I think was Cubase 6 installed on that computer. I had been using Cubase on that computer for years and have a lot of files on it. Can I activate Cubase on my new replacement computer?
I have much of music on it and periodically I edited songs that I had recorded and would like to transfer to the new computer. I was able to save the wma version of the songs
