At very beginning of level where you have to grapple down the pillars and then pull out the block, when i come out of there and go to jump on block to get to ledge, i cannot jump on the block. So i went to the one i pulled out and then onto block, but will not let me jump up to ledge. I have tried every way i can possibly think of. I seen this as a glitch on you tube, but no solution as to how to get up there. PLEASE any help appreciated. Thank you!
