Hi, I have the same problem. After seting up windows on a PC and reinstalling Opera and trying to sync I dont get my bookmarks anymore (no problem with syncing passwords, settings, history etc).
Whe I log into auth.opera.com (thats where the sync.opera.com link is leading me) my bookmarks are still there (but it looks totaly chaotic: trashbin folder, the bookmark bar folder, my bookmarks folder etc. are all there twice.)
Is there a way to get the bookmarks from auth.opera.com as a file or something?
