My PC with Thunderbird installed and running shut down suddenly as a result of a fire on the motherboard. I was able to recover the hard drive and copy most of my files etc to a new machine. I followed the instructions for transferring the thunderbird profiles from the hard disc to my new machine. Although the transferred profiles on the new machine appear to contain folders and emails, they will not load into the programme and the thunderbird display remains devoid of any user data. I then tried to do the transfer using MosBackup. This told me that the profile was damaged. I know that migration should take place with thunderbird shut down, but unfortunately the shut down of the old machine was sudden and catastrophic and did not shut down thunderbird in a planned way. Please can anyone help.
