Well, I played paintball this weekend and I used my Halo I just got. It worked fine for awhile, but then when I stopped shooting and it wasn't feeding, the LED light on the back was flashing red and green. Even when I started shooting, it wouldn't feed anymore and the light continued to flash. What is the problem and how do I fix it? BTW, I ran another hopper full of pb's through it without the gun connected and then stopped the balls from coming out and it did the same exact thing. Thanks in advance.
