Picked up an Ion kit today. Hooked it all up and things were going fine except the red pad was REALLY unresponsive. So I tried different cables. No change. Just tried using a different pad. No change. I'm pretty damn sure it's the brain just having some sort of short or not being sensitive enough. I have to REALLY whack the red pad to get a decent response. It also seems to get worse the longer I play. When I start it seems to work alright, but as I play for more than an hour or so, it's unplayable.

I am pretty sure it's a defective brain. My question now is - who should I contact and how long should I expect for this to get remedied?
