ESRI Route Service for Locate Widget

To All FlexViewer Users and Developers:

By default from the Locate Widget download, I am using the follower routing service:

<routetasksolver>http://tasks.arcgisonline.com/ArcGIS/rest/services/NetworkAnalysis/ESRI_Route_NA/NAServer/Route</routetasksolver>

According to the following url:

http://www.arcgis.com/home/item.html...17bf74b5f300fd

The above routing service is on extended support and I should use the newer World Route service instead

http://route.arcgis.com/arcgis/rest/...Route/NAServer

but when I try to access this URL or just http://route.arcgis.com/arcgis/rest/services

I get Error: Services Directory has been disabled Code:403

Does anyone know the proper URL to access this newer routing service?

Any help or hints are greatly appreciated. Thank you.
