Just redownload a new FD. FD4 (if you don’t have it) is a major improvement over FD3. And if you ever plan on working in AIR or Haxe then the most recent versions of FD have better support for them, regarding code completion, syntax highlighting, etc.
If you only want to update Flex, just download the latest version and in the settings, go to AS3 Context and set the path to the folder where you extracted the files.
But if you still have FD3, doing what UG said would be better.
