Tahir,
I checked your samples and there are not any rout records between the two points what you want, I checked the problem by the RoutingExplorer, I found out the problem is from your shape file, there are several roads are not complete, they are broken, so it cannot found out the exact routs for you, here is the screen shot below to show you the shape file problem:
You can open the RoutingExplorer and set the start point to -85.2334, 12.9292 and set the end point to -85.2228, 12.9238, there are no routs records between these two points because of the broken roads that shows to you in the screen shot above,
Any more questions please let us know,
Thanks,
Scott,
