>need new download
Go to Adobe and log in... Your download order history will have a link so you may download again (according to what I have read in other messages)
If you did not purchase via download before, you will need to contact Adobe (this is a user to user forum, not Adobe support) to find out if they will be able to give you a link
The correct forum to ask your question is http://forums.adobe.com/community/download_install_setup
You can locate the Creative Suite 5 download files at http://prodesigntools.com/all-adobe-cs5-direct-download-links.html. Please make sure to make a back up of the install files in case you need them in the future.
