you'll probably need someone to download your file and fix it but you might be lucky and get away with:
1. delete nothing in the duplicate fla
2. import your new image to your library.
3. on the timeline that contains the old image, click to select the old image.
4. in the properties panel (windows/properties or windows/properties/properties), click swap and select the new image.
Thanks, but that didn't really work.
I have packaged up the fla, and then added the new graphic to a RAR if someone is interested in taking a look. I really need to understand what is going wrong since he wants me to make 5 more of them (sigh).
Open up both RARs to see the original, so you can see what it normally looks like. I can get the new image to show up just fine - but it is breaking the button so it doesn't show up, and doesn't seem to want to link to anything.
Thanks again for the help!
(i don't usually download and correct files unless i'm hired. maybe someone else will download your files.)
