I repaired mine by cutting a 2x2 the same length (tight fit) as the height from the floor to the top of the door track...after taking the door off as donn0128 said, I drilled 2 holes in the 2x2 for 2 1/2 in #8 wood screws and pushed it into the door cavity all the way to the wall wedging the track to the ceiling...then I used a long drill driver extension to drive the screws in...not the easiest way to do it, but it worked and the door slides like it's supposed to...sorry I don't have pics.
