Possible to extract source files from my swfs?

A little over a year ago, I suffered a hard drive failure. As it happens, some of my directoties were not archived/backed up. I have about a dozen swfs that need to be revised due to a client changing its name.

The swfs were loaded dynamically into a main move. I have tried to import them into a .fla to extract the images, etc., but seem unable to reverse-engineer the swfs. I’d hate to have to re-do all of that photoshop work, does any have any suggestions? (I’m using Flash 8/Actionscript 2).
