NOOB Question no playing a Flash 5 to 8?

OK here it goes, I purchased the Flash effection CD and am trying to customize some of the fla’s to work with my new flash pages… All of the files are Flash 6 and below, and when I try to publish the files with version 8 their effects don’t seem to work…
Even if I take the files straight from the CD and up the publish to 8 and actionscript to 2.0 the fla’s won’t work.

I’m sure it’s an actionscript issue, would I get into trouble is I post the script for people to see what’s up?

Thanks,

Lic
