Advice about working on Open Source files

Sorry if this post is in the wrong forum.

I’m trying to learn more about flash, and have found a couple of useful sites.

However, I’m having trouble working out how to use their source files, and wondered if anyone here might be able to help please.

For example:

This page:
http://www.everydayflash.com/blog/index.php/2008/04/16/five3d-first-impressions/

I can’t work out how to compile it - I know I need the Five3D files (http://five3d.mathieu-badimon.com/), but even when I download that, and then create a .fla file in the same directory, nothing happens.

I am probably missing something very obvious, but I can’t work out what to do.

Same here on this page:
http://pixelwelders.com/blog/actionscript-3/2008/five3d-textcloud-as3-tutorial-and-source/

Even with the Five3D and TweenLite files in place, I can’t work out what to do.

On files I have downloaded (e.g. from http://five3d.mathieu-badimon.com/gallery/fluo/

There is a .fla file, but there is NOTHING in there that links to the .as file - there is no ActionScript at all I can see if the FLA file, that links to the .as file.

Any advice / help much appreciated.

Thanks
