My newly installed TB has disappeared from my computer portable 64-bit Windows 8.1. How can I prevent this from happening again?

When I installed new cases of tuberculosis 'portable' a few minutes ago, all seemed well unfold. I downloaded an accumulation of messages from my server and started the implementation of filters and the archive folders. Suddenly, TB froze and then disappeared! When I clicked on the icon, I was presented with a blank, new, TB and asked if I wanted a new email address, etc., as I had been before (and refused). I went ahead and download my messages in the 'empty' TB, but how can I keep the content to disappear again?
I wonder if this is a problem with the wrong Windows 8.1. Any ideas?
Thank you

The examples I have seen are Windows 8 back to a previous state when something goes wrong with the boot and Thunderbirds gets cancelled out of existence. Creating a restore point in Windows after you install Thunderbird could help.
