User blog:ForNeverAfter/Assassin Creed I'm Stuck

Hey i am stuck and need help. Im towards the beginning at the first mission where you actually need to shoot were you have the two guys helping you. I picked up the musket and shot the people but now i'm at the next checkpoint were it says to press L1 to Aim, it increases your range. Well i bought the handgun but i've already fired it and i dont have a musket in my hand anymore and it won't let me move so i'm not sure what i'm suppose to do. when i hit reload your last checkpoint it just starts me at the same place. if anyone can tell me what i need to do it would be greatly appreciated
