I placed the file as instructed and tried using both start buttons.
Under Populate Depth, I had a response on 8 articles (which I think are all I've got on the test server).
Under Fix Structure, I had the process "act" like an update was being accomplished, but no verification at the end. I tried this with the * (which I'm assuming is all articles). I also tried it with "Select Component" using EasyBlog and Joomla Article. I also used the choices under the "Select Article". Again...... I had a "progress" indication, but no verification of completion.
To repeat, all this is being done on a test server, but I would think my live site would react the same.
Also as a note: the downloaded file was a "copy and replace" into the folder directed by StackIdeas.
