So i have been going through the mission mode in UMvC3 and i have been running into some problems. a lot of the missions i try i do the right thing and it doesn't register. in the Iron Man missions, the first one is to use a Unibeam H on the Ghosts n Goblins guy (whose name escapes me). i do that and nothing. anyone else running into this problem.

now before people say it, no i am not just saying this because i suck at the game. i can throw a fireball and that is really all you have to do to pass this mission. the later ones i do really suck at, though.

Are you sure you're doing the H version? Check your controller settings just in case you've assigned H to another button by accident.
