Finally got a new PC. Win 10 64bit. On old computer, was win 7 then moved to win 10. 32 bit OS. T-bird has been working great on old system. I found the "how to" migrate my DB and info to new machine. Thought I followed instructions well but did not work. On opening T-bird it was asking for which profile to use and the first time I selected default which did not allow any of the old data to populate. Upon re loading the T-bird folder in the roaming folder I selected something else (don't remember) and all info populated. Everything worked well until I rebooted the machine. Then it was gone. I then tried copying the profile file and using that and now T-bird doesn't even open. I get a window stating "no profile found". Tried un-installing T-bird and re-installing, no luck. Same issue no profile. It is now beyond my paygrade. Help! Thanks, J
