Check the simple things before you get rid of it.
Good batteries in the reloader? It could just not be feeding.
Are you using it correctly? Turn it on first in a quiet area (under your jumper will do) let it turn, then put in the paint and it'll pre-load.
Put it on setting 1, this is easily enough for 15bps ramping so im sure it'll do for your ego unless its a bit bouncy
Lastly, is the drive cone on correctly? If you push it clockwise, does it tension on the spring?
If you check these, and it still doesnt like your ego, i'll have it
