Due to a recent major security breach I started changing all of my passwords on my main desktop, I did not have sync on at the time. I then opened up my work laptop (again unsynced) and decided I should really use the sync feature to transfer my 500+ passwords onto my laptop for when I travel.

When I got home that evening, I turned on the sync feature on my main desktop, unfortunately it pulled all of my compromised passwords from my laptop and overwrote the ones on my main desktop. Is there anyway to restore my pre-sync passwords and ensure that they get transferred to my laptop instead please.
