I can't go through doors

[7zelda7]

Several days ago when I was playing Zelda OLB, I noticed that somehow, the game will not let me go through any doors. I started file 2 to see if that file have this problem, and it doesn't. I don't want to start the game over, so is there some way that I can fix the game so that I can go through doors and not have to start over? Thank you.
