Help Me!

Yesterday i got my 68/4500 filled up full and i shot about 1 and half hoppers worth of paint and it went empty. I was roping my promaster and then i didnt notice it using air rapidly and then when the air was all out, BANG! It started to leak down the barrel and my entire gun went ice cold. Any suggestions? Think i should have my local proshop look at it? I believe my dwell is at 8.
EDIT: I got lazy with my battery change and i didnt remove the clamshell... and it might be pushing up against some of the wires... would that effect the effeciency at all?
