I just formated my laptop, when was asked to give a name i just ended up writing the same one as the last one, then i logged in in Sync and all my data was lost, passwords, bookmarks, history, everything. I'm pretty sure it was because the laptop had the same name and was registered as the same device in Sync at the time of formatting. In my smartphone the data was gone too. Is there anything i can do? or it all lost?
