for better understanding you have to post the complete error, oaste the terminal output here so we can know what it is in particular. By teh way probably you forgot a wall or there are two blocks connected with inconsistent faces (different size or meshes).

Thank ArathoN.

sorry i can answer you only on the weekend, by the way control if you set up all the faces and that are properly connected and if you can post an image with teh geometry you considered this would ease me into discovering teh root of the error.
