Thankyou! wonderful!

I recently reinstalled windows 10. When I logged into my opera account and began the sync operation, I recovered all of my bookmarks etc that I had before, but my old speed dial did not download. Rather, it uploaded the new (default) speed dial to my account. How do I recover my old speed dial. I can see the upload cache in my account, but I have 650 speed dial pages (mostly in folders), so I really don't want to loose them, nor manually redo 650 pages.
Thanks.
