If this is the way you intend to continue formatting your text file, the only thing you need to change is the string pattern in the Results.Regex action.
My command used the pattern (.+)
Change that to /(.+)
Should work.
[edit: it should have still worked with the original pattern, but as you say, announcing the / at the beginning (the new way cancels out the /). Not sure why it didn't work unless it couldn't find the file at the file path specified.]
