It's not working and I know what could NOT be the reason

[jadedusoliel.livejournal.com]

So this "lady" calls in because her equipment is not working. All through the call she keeps telling me what is NOT causing the problem with such comments as "well it's not X that's causing the problem because if it was I would know". Right you, an untrained person, would know even though you called me, a trained professional, for help. GRRRRRR
