I have noticed that some people are having problems with the PAI package for removing default commercial traffic.
After reading the instructions carefuly I got it to work.
You have to make sure that the PAI installer is editing the default traffic file, not ones that have been created for addon traffic. Here's how:


When installing the remover package select "Custom installation" and click "Next". Then select "Customized naming and locations" and click "Change ...".
Select "Apply following suffix" and type 030528 in the box to the right. Click "OK" and continue the installaiton as normal.


With any luck the next time you start up FS there should be no Orbits and Airwaves in sight.

NB. This works for FS2004 but I'm not sure for other versions - Good luck.

If you only use the commercial traffic remover - Yes.
