I am using the Free Download Mode but High Speed volume is still being deducted.

Some files can unfortunately not be downloaded using the "Free Download Mode". In order to complete the download some newsreaders automatically switch to the "Highspeed Mode" if your settings allow this.

If you do not to automatically switch between the two modes please check the settings of your newsreader and uncheck the "Automatically switch to Highspeed Mode..." (or similar, depending on the program you use) box.
