Why do you want him to try to remove DOBOROG

My thinking on that was that a setting may have become corrupt. It's the first thing to try when something strange happens. Renaming the folder allows Clone Drone to regenerate any files involved. If that makes no change, you can re-rename or restore the folder to return your data. - A clean reset is the easiest way to rule out corruption, and then once that is out of the way, I can move down my own mental "trouble-tree" for what to try next. That's generally a pretty sound approach to resolving these issues. :-)
