If you purchased it from the Adobe Online store, you should be able redownload the software from your account. Then you should back it up to an external drive or to DVDs so that you can restore it again if you need to.
Simply download and install the trial software, and use your serial number to activate it.
But always, always save the download someplace away from your main drive, as MichaelKazlow suggested. There's no guarantee that you will always be able to get the download again.
I was happy to discover in the Elements web site information about my order and the key to start the new program. Thanks for the suggestion. Jon Harrington
