Some suggestions;

1. You used eq2ui_mainhud_tracking.xml for a the file name and not eq2ui_mainhud_tracker.xml as your post said? If you used eq2ui_mainhud_tracker.xml then it will not work because eq2ui_mainhud_tracking.xml is the correct file name.
2. You did extract the files before putting them into the ProfitUI folder 1st correct? I also notice one of them had the tracking file inside a folder, so you would have to extract only the file not the folder/file combo on that one.
3. After you have extracted the file, visually verify the file is in the ProfitUI folder by using windows explorer or what ever means you use to do such tasks.
