Firstly, have you created an object named Particle?
Secondly, I doubt there is a function named setBitmap on particle datablocks.
Thirdly, you cannot use .cs scripts as particle bitmaps.
Fourthly, you are not transmitting the changes to clients.
Fifthly, you are mentioning the "admin orb bubble". The datablock of the admin orb bubble is not named Particle.
