After reinstallation of Windows and reinstalling Firefox, i did the firefox sync with (i think) a newly generated key, because the old one was lost. after all the steps where completed and hitting the sync now button, no syncing was done. no old bookmarks links or directories we're restored. please help! thanks.

You can't get your data from the Sync server without the proper SyncKey, which is used to encrypt your data going to the server and decrypt it when it is downloaded back to Firefox. When you obtain a new SyncKey for an account, the server is wiped of all your data so it doesn't fall into the wrong hands.

Same for me. I have reinstalled windows. I tried to restore my bookmarks (previously Sync with FF4) but it's not working  !

However the Sync restored my passwords...
