I'm reluctant to suggest this, because it's kind of a down and dirty fix. Before you do anything, take a straight edge (preferably ruler) and lay it on the fret. If it rocks back and forth, the fret is high. Also check to make sure the truss rod doesn't need to be adjusted. The truss rod shouldn't be used to fix the action, but it can cause buzzes if it's not properly set.
Finally, if everything else checks out, use an emery board to lower the fret. Check it frequently to make sure you don't sand off too much of the fret.
