Sorry, Myrnice. I don't actually use these programs, I just play with them. And did you mean that it is *now* the domain of Ruth. :-)
But, seriously. I think it is time for the person with the problem to stop, take a deep breath, and consider contacting contacting Melissa, and or reinstalling the program.
I believe that I once caused a similar problem in playing around with automatic launching, and I re-installed before Melissa suggested re-indexing. My previous instructions of deleting the path may have damaged Uftree.exe.
But then I am only speculating, because I really don't understand what happens here. However. . . IMHO, nothing short of a reinstall is going to fix it now.
