Profile copy failed
I had a motherboard crash, actually it died. New motherboard and of course Windows 7 spat the dummy. Copied T'Bird Profile, is 343MB, and pasted into Appdata/Roaming/Thunderbird/Profiles, renamed the profiles(ini) to read new Profile. Copied Profile also into Appdata/Local/Thunderbird/Profiles. My Profile just not seen, T'Bird always asked as if new user.
