Mr. Williams,
Thank you for your reply. That is a relief to hear, but man, it really looks like all my work in the timeline is gone without a trace! I find it ridiculously peculiar myself and I’m confident we should be able to get to the bottom of this.
Let’s start with what I’ve tried. I have double clicked on the project within the event. It is blank. I’ll show you a screen shot:

I’m trying to recover the work I did in the event called ‘Potato Boots’
Again, my concern is I created the Library ‘March 2015’, I created an Event within that Library called ‘Potato Boots’, I created a project within that event, but I think I did all of my editing outside of that project’s timeline. That’s why when I closed the Library, the timeline disappeared and all the work was lost. And thats why when I click on that event’s project now, the timeline is totally empty.
Again I hope that’s not the case and that what I’m describing is impossible.
I’m eagerly awaiting some additional guidance. Thank you for your help so far.
Cheers.
