Flash Backward Compatability! Help!

Hey everyone, I said a while ago that I found a problem with flash that I, and many as I am now discovering, have practically beat our computers over.

Flash CS4 WONT SAVE TO FLASH 8!!!

Ouch. This is a major problem for people like me who like to help others, and then give them back the file.

I currently am in that situation, and I understand that flash CS3 can save to flash 8 .flas.

Would someone with flash CS3 please transfer this file
into a flash 8 fla?

I would be forever thankful.

Cheers All!
