Hello!
MarkV, thanks so much for trying to help bettingneil!
You know, Neil, by looking at your screenshots, I can see that the Reimport option is enabled (see the attached image - a copy from your screenshot with this area highlighted). Normally it should be disabled (see the second image attached - a screenshot from my copy of MF Pro). This means you pressed the Import selections for auto-trading at least once, and if you imported from the wrong file, or if the file's contents have since changed, after the next reimport the program will disable all selections.
So MarkV's first question was, are you importing selections from a list? Please respond to this question.
