Re: My library doesn't work anymore

For possible future situations like this, some stuff I do...

--- I always make backups of my emitters every time I change something in them. I have a shortcut in my main emmitter folder to the backup location and just drag the most recently tweaked one into it.

--- I make and name my own "best of" collections by type keeping the originals in their own folder. That way, I can always go back and rix things do one degree or another.

Last but not least:

--- Projects are really the best place to edit and fine tune emitters: far more manageable with multiple viewable undos. Then if a real winner I want to archive, I can save it in and/or as a library.

I hope your situation works out.
