I have had the JRX/Rail Racer set for a while, but never combined them. Until a couple days ago. i am stuck on one step. been watching videos to guide me, but i can't get a certain part of Rapid Run to slide...it is severely stuck. there is a screw there, but i can't get any 'driver in there to loosen it. any ideas? anyone have trouble with it? this is the Korean Giftset, just so you know. The pic below points out where i am having trouble:
