If you look at the pipe.x file you will notice it is drawing a cell as shown below
{
draw skip to x1 y1
_d_scale = Drainage Link Rise
draw cell = pipe
xs = _d_scale
ys = _d_scale
}
You need to make sure you have a cell library attached that has the cell called 'pipe' in it. If not then replace the cell name with a cell that you do have and is attached in a library to the dgn file or in you ms cell list.
