We have a an old hybrid projector CD(PC/Mac compatible) that basically links to/opens a bunch of PDF files on the CD. The source fla was probably authored in Flash CS3 or earlier.

We are trying to publish updates to the CD using Flash CS5.5 and the CD works fine on a PC. On the Mac, the module crashes 5 seconds after launching any PDF giving the error: "Flash Player quit unexpectedly."

Any suggestions would be greatly appreciated. Thanks!

Additional info:
Authored in Actionscript 2
Uses applescript to launch PDFs on Mac
Uses jstart exe/ini files to launch PDFs on PC
Last working version authored in Flash CS3/Flash Player 8.
Tried publishing mac projectors using Flash Player versions 8-10.2 (All crash after launching the pdf)
