[RMVX ACE] SPRITE WON'T MOVE

Everytime I create a game recently something's gone wrong and I really feel like just giving up on RPG Maker completely (yes things are just getting that bad) first the file is corrupted and I have to re-make my entire game, but now when I transfer my player to a certain tileset, they just don't move when they're on the map! Ive tried eveything i can think of! It's a modern hospital tileset my pixel graphic artist created for me, and it was working perfectly until just about an hour ago!!!
It allows me to walk whenever I press the 'walk through walls button' (AKA 'CTRL')
but if I don't have that pressed my sprite just won't move, PLEASE HELP!!!!!

That sounds like the passability settings for the tiles are such that the tiles you want to walk through are currently set to impassable.

No, that's the thing I have the floor A5 tiles to passible. :T
