You can load Elements 9 by going to this website and following the directions:
You will need to know your serial number to activate it, which you can find on Adobe.com.
Login and click on "my adobe" and then "my products and services".
Click the triangle to the left of the product in question to view the serial number.
You get two activations with the license, so depending on how many times you have installed it, you may need to deactivate the program on your old computer before activating it on you new.
If you have activation problems -- http://www.adobe.com/products/activation/
This forum has a focus on sharing on storage, and the transition from photoshop.com storage to Adobe Revel. If you find you have additional installation issues, you might want to check the Adobe user forum called download, install and setup. It can be found at: http://forums.adobe.com/community/download_install_setup
I hope that helps!
