Problems please Help

Hi I have been working on a bit of flash work for the last couple of hours, then I went to add a video and realized that it was optimized for flash 5. The problem is that changing it to flash 8 breaks the actionscript. Could any one help me fix it? I’m really a newbie and in need of help. anyone that could fix this really would be making my day. I have uploaded it with flash 5 settings but if you change it you can see where it breaks.
