What frame did you get? If you got an electronic frame that might be part of the problem.
When this happens, disconnect your gas source CAREFULLY and the gun won't be able to keep wasting Co2 through shooting.
It sounds like the output of your tank is screwed up, discharging more gas per cycle than it should. That and your trigger might be so sensitive that once is starts shooting the vibration from the shots makes it go off constantly.
