I need to restore my computer to factory settings. I don't have my disk for CS4 anymore, but I do have the serial number. Is there a way to download it after my computer has restored? Or is there a way to save it somehow?

Follow the instructions closely.
If it works, backup, backup, backup. There's no guarantee these links will work next time you need them.
