Exchange CD Version For Download Version?

I bought Ccleaner Pro off of Newegg since I had some credit and a coupon to purchase it with. I love the program and am very happy with my purchase but I don't want to keep track of this CD and key that it comes with just to keep the program around. I was wondering if I could give the CD key to support or something and get a download version so that I can use that instead of having to keep track of this CD.

The versions offered by Newegg seem to be packaged differently from what we (or I) are used to in the UK, where it's download only. I suggest you contact your support manager at Piriform for advice. Can you, or have you, set up an account at http://www.piriform.com/support ?
