Sparkweb.swf to fla?

I’d like to be able to brand the login page of sparkweb, but all the 3rd party programs ive tried have failed when converting swf to fla.

Any suggestions or is the FLA available someplace?

Thanks!

SparkWeb is built with Flex and as i search the svn trunk of its source code, i only see .as files, no fla files. http://fisheye.igniterealtime.org/browse/sparkweb/trunk/SparkWeb/src/com/kebinge r/flexlayout
