Whenever i add something from the Sapphire Plugin, After Effects either closes without warning or any explanation, or it says it doesn't exist. Can someone help? I've tried deleting and reinstalling Sapphire, I've tried uninstalling and reinstalling After Effects, I've even tried resetting my iMac to factory settings. Nothing has worked.
Make sure the Saphire plug-ins from Boris FX are up to date, your version of AE is up to date, and that your system meets the minimum system requirements. If all of that is good try opening up the Project settings and changing the rendering settings in the first panel.
