My KGO has been great and working fine for weeks, until today. I have a Vision Clearomizer plugged in that wont fire, when I hit the button it just blinks a few times and then shuts down. The same thing also happened to a C8 Cryptonite, but it works if I use a fluxomizer I have. I have tried pulling up the center pin on the battery and on the vision but it didn't help. So what exactly does the blinking mean, and does it mean that the cartos have gone bad, should I just trash them
