Following any upgrade/update, be sure any required plugins are installed in the correct location. See:
And plugins often have to be updated to new versions to work with newer released/updates of FMP.
Sometimes you get no plugin-related error in FMP until you open a file or run a script which relies on a specific plugin.
I removed the ccPivot2 plugin and all seems to be good.
That probably means the plugin version was no longer compatible with the latest FMrev.
Clearing out plugins is a useful tech support test when a recently revd FM version crashes.
If you find you still have a need for a plugin that no longer works, contact the plugin developer to see if it will be updated to work with the latest version of FM. It's up to plugin developers to keep their stuff working....
