Obstacle makes domain deformed

Hi there, I think somebody asked this before. But I couldn´t find an answer.
MY fluid simulation is ok, but when I added an obstacle my domain was deformed. http://img219.imageshack.us/img219/7203/picture2yn.jpg
The Uv Sphere is the fluid, the cup is the obstacle, the strange thing in orange color is the domain deformed by the obstacle. I was trying to do Blender Cookie Intro to the Fluid Simulator – Round 2 tutorial.

Please HEEEELLLPP!!!

Ok, I found it, a noob issue I think. I had to change the temporal folder where all the bake files are created, because It reads the previous files created there from other projects. I didn´t know this. xD
