Can you upload your Director file somewhere?
Thanks for the quick response and sorry for taking so long to answer.
In the end, after lots of testing, I installed Director on the specific computer. Surprisingly the movie didn't progress on frames even in the author mode. At that point I decided to reboot the iMac, and that fixed the problem
So anyone who's having Macintosh and Os X with the projector not starting, being stuck or not progressing in the movie, try restarting the machine.
Hi Sean and others that may come across this post.
The issue appears to be a known bug that happens on Macs if Director is left open for more than 25 days. Some timeer thing stops functioning meaning the playbackhead soes not progess through frames. A restart gets Director working again.
I helped Ceitna outside of teh forum and managed to find out that the issue is in the Adobe bugbase.
