Cant use arrow keys

[DocileYandere]

After using some strange tool I decided to try out the new characters I added to my  game but for some reason my arrow keys wont work (Like i cant switch between characters, or modes).  My arrow keys do work..they just dont work on that specific mugen game.  Ive tried using them on my other mugen games and they work perfectly..theres just a problem on this one.  Does anyone know what I should do?
