I recently needed to format my computer and change my Opera account password. I installed Opera, and logged into the account, but when I went to synchronize my data, the browser demanded a password I had never seen before: "synchronization password (passphrase)".

I thought the solution would be to click "Reset Passphrase". All my data, including all bookmarks (favorites) and more than 200 passwords have been lost or I can't find them anymore! I would like to know if there is any way to reverse the situation.

Sorry for my bad english... my native language is Brazilian Portuguese.
