Save file back to Flash MX 2004 Pro?

I have four FLA files that someone saved in a later version, now I cannot open them in MX 2004 Pro (I need to use them in that version). Does anyone know where I could get a trial version of CS4 or otherwise how I can get these files back to compatibility with MX 2004 Pro? I have CS3 but that won't open them, I'm assuming CS4 will.

Thanks

Flash sometimes sucks:

1. Get CS4, save to CS3
2. Get CS3, save to Flash 8
3. Get Flash 8, save to MX 2004

you've got yourself a huge problem, because Flash's older version aren't available anymore, I think!

Wow, that's amazing. Anyone on this forum with CS4 for Windows that could save 4 files back to CS3 for me? Then I can at least open them in CS3 format.

Thanks

Me again, someone converted them back for me, thank you!
