The only thing that comes to mind is that in the replacement process one of the pulleys ended up at an angle to the rest....they all have to be parallel with each other.  An example would be a belt sander....has an adjustmen knob that changes the angle of one roller in relation to the other to keep the belt tracking straight.

Which of the pulleys moves to release tension and allow the belt to be changed?  Alternator?  For S&Gs check its alignment with the others.

Finally, maybe it is a bad belt?
