Lost shortcuts, on all computers: New Upgrade or DropBox?

Describe the bug
I lost all of my shortcuts from two computers and a bootable hard drive. After booting into the bootable hard drive none of my shortcuts worked. I opened BBT and it looks brand new. I booted back into my main computer and it too doesn't have any of my saved shortcuts. Then I head to my MacMini Media center, it too doesn't have any of the saved shortcuts. I did have beta - dropbox backup enabled. Is it possible to recover?

My main computer was upgraded to the newest BTT, but I don't think the Media Center or the Bootable Drive was upgraded.

Mh, you could check whether there are some of the automatic backups still there.
