Did you make sure not to get co2 into the valve? Make sure the tank is below the gun. Getting co2 into the valve will cause it to over pressurize and vent out like that. Let it sit for a few mins and reatach the tank.

Or:

Sounds like you either got dirt on the regulator seat, or need a new one altogether. It is the clear rubber disk which is right in the middle of the regulator and valve assembly when you unscrew the two pieces.
This part comes in the parts kit, just make sure you put it in the right way.
