It's most likely a rigging problem, but to know for sure I need more info. What is your Bow draw weight, arrow weight, draw length, chrono speed if possible? Where do you currently have the launcher arm cable tied into? Is it tied into the top of grip, middle of grip, bottom of grip or slide? Advancing the spring tension should be your last resort. Since it's the weekend, I may not be able to get right back to you...I'll be out shooting my QAD rest trying to keep it from getting fletching contact. HA! Just kidding.
