If you're not using an "open" stance, you might consider doing so. Also, if this was not happening with your previous bow, and you still have it, try shooting it again and pay particular attention to your bow hand grip and bow arm position. If the bow grips are different, the new bow grip may be causing a change in your wrist/arm angle??
As McD said, your bow arm doesn't need a whole lot of bend, but it shouldn't be locked, as that action generally rotates the lower portion of the inner arm into the path of the string.
Good Luck & Have Fun!
