I've had both of these issues, with the symbol timeline going blank sometimes if you open the symbol from within the Library instead of the elements all your animations are there.
The other issue with the C++ exception is something I flagged but when I updated my Edge Animate. See this thread:
Looks like Adobe are trying to fix the problem.
Thank you for the reply, i tried both ways but it didnt show the timeline! So I gave up on it and installed the previous version But I had to do the project all over again from scratch. maybe part of this problem is also edge commons script that I'm using in this project which might not have been updated to work with the latest version. I found this other issue that acctually corrupted my original files of the project. when you open a project made from a previous version, it saves the project with the suffix upgraded but it also at the same time corrupts the original files. When I try to open the original files it says it's made from a newer version!! The
Can you share the edge project files so that we can trouble shoot the issue?
Thank you very much for the offer, i've finished that part with the old version already. But i have another clients file that was made from previous version that has to be edited, i will try editing it from the new version and i will let you know if i come across the same issues.
