Hey sabawarnali,

Sorry for your issue!

Can you tell us the version of After Effects that you're using? FAQ: How to find the exact version of After Effect... - Adobe Support Community

If it happened after installing the Newton 3 plugin, then it's most likely the plugin that's causing the crash. I'd suggest two things:

1. Uninstall the plugin
2. Contact the plugin manufacturer and check if the plugin is compatible with your version of After Effects

Thanks,

Rameez

i have the latest version of AE

anyway I contacted the plug in developer and they provided me with a upgraded version for it, and the msg didn't appear after I installed updated version of the plugin 

thank you for your help
