After a sudden power outage my calibre changed...

So yeah, I had a power interruption of a few seconds and my computer restarted. When I reopened my Calibre installation it was changed. For a moment I thought it lost the database... but no. It looks fine. Everything looks fine actually oddly enough. My books are still there. my database for the books is still there. my plugins are still there. even my custom columns are still there.

The only thing that changed and is bugging me (at least that I can tell) is my toolbars got reset (I've already tried to remake them from memory and I failed. They feel OFF but I can't remember what they were exactly from before. And the button on the bottom right labeled layout that gives a popup of different options like tag browser and etc. And the dimensions of the cover/metadata/description for the books. I hadn't installed an update to calibre afaik so I don't know why everything changed. As far as I can tell, the rest of my preferences are still intact.

So basically I want to know if a) there is a backup I can restore b) how to manualy go back to the old school style for the layout options on bottom right c) restore my toolbar from a backup or something :cry:

Oh! And I had a new copy of the quick start guide appear with today's date. Made me think it thought it was a fresh install. I've tried to restart and no change.

(I've obviously filtered my library just to show the quickstarts, don't need to see my books. I was in the process of (or finishing) a fanficfare book update but I think that was finished in the background possibly when the power flicker happened. Shouldn't have affected the layouts I'd think, but I could be wrong.)
