I started my use PTB with version 1.0.5 beta.
Migrated to PTB 1.0.7 beta by extracting the new version to its own folder named "Portable Thunderbird". Afterwards I copied the complete "\profile" folder into the new location.
As far as I can remember, everything worked just fine that way. I had my two accounts properly "imported", as well as "subfolders", into which I manually used to move received mails, depending on who sent me that specific mail.
Yesterday I had to add a "line" to that prefs.js file, of which I found 6, named prefs.js and prefs-1.js to prefs-5.js, that I found in a forum somewhere on the internet, that dealt with a timeout problem, since I had problems receiving large mails. This timeout value was changed to 600 or something like that, but I don't think, that this is important to what happens now.
Yesterday I arrived at home, after having used it throughout the day on another machine, plugged my external harddrive in and then this happened:
PTB 1.0.7 beta asked whether I want to create a new e-Mail account, RSS-Feeds and so on, as if i hadn't used it before. I immediatly shut down the program via the taskmanager to prevent loss of data and copied the "\profile" folder to a save locatrion on my desktop pc. It still had the size of around 440MB including folders named after my accounts and those "subfolders" named after senders names, like explained above.
I have tried the above described "migration"/ importing method by re-extracting to a brand new folder and inserting the "\profile" folder into the "\data" folder.
Tried the same on a second run, by first starting this "blank" version of PTB, created my two accounts and did exit the program. I did not use the checkmail funtion. Then I moved the "\profile" folder to its dedicated loaction under "\Data" and started PTB again, in hope that it would work this time....
Tried all the above also with version 18.104.22.168 en/us. The same happened.
Now what can I do?
Thanks to any kind of help, that leads to the access to my mails.
