just tried what you recommended without success unfortunately.
in the folder that i am trying to open in the AFX project and sound in AIFF format.
i double clicked on the AFX project (and tried the other way listed above) and a box comes up saying
“After Effects: this project must be converted from version 5.0 (windows) and will open as an Untitled project. The original file will be unchanged.”
then i click ok, new box.
“after effects warning: 1 file missing since you last saved this project.”
click ok again
the project comes up in the project side bar with the .aiff file missing, i got back into the folder to add it into the composition again and
“after effects error: the file format module could not parse the file
(45::35)”
and then back to square one again =(
any thoughts now?
