All my connections have disappeared

Hello, Yesterday I used DbVisualizer as usual, without any problem. Today I open it, and surprise!, all my connections have disappeared. The New Connection Wizard is displayed. I had about 20 connections defined... now 0. It's the first time I encounter a serious problem with DbVisualizer. Looking at .dbvis\config70\dbvis.xml, I only find the General and Drivers sections. The Databases section is empty. Idem for the dbvis.xml.bak file.

I've used DBVis every day for years and have seen the same thing happen probably three times now. I figured it was perhaps due to accidentally closing or killing the program just as it was editing the XML file but I can't be sure as it hasn't happened in ages. My solution after the first time was to install Tortoisegit and use that to commit a backup of my XML file (and my bookmarks, license file, etc) each time I made a major change to it. I guess you could just zip the XML file to perform the same functionality. I only used git because I wanted to have a detailed record of when and why I added new connections, bookmarks, etc.
