Frozen Character! please help!

hey everyone
i’ve been makeing a fan-made game (i do not intend to make money off this, and i do not claim the characters belong to me). i’ve hit a bit of a problem. the character is…locking up. i can’t think of anyway to describe it. here take a look. in the game engin, let the character sit, nothing will happen that shouldn’t, however, hit up (move forward) and she moves but the actions stop. you’ll see what i mean. but hit space (jump) and it still works but it get’s stuck in that last ‘pose’.
