Lost all emails and accounts on Thunderbird for U3
have been using Thunderbird for U3 on my U3 USB stick for sometime and have multiple email accounts configured. Now, suddenly for some reason - and I am not sure why, may have been a virus or something -- all teh emails and email accounts are gone.
When I open Thunderbird, it shows up as if I had just installed it for the first time and is asking me to set up email accounts etc.
I did not manually back up any of those emails. Are they somewhere in a folder? does Thunderbird have them somewhere?
