Answer 1

As i remember a limitation for request to google maps api is 250 per day for one application. I also remeber that google can stop responce when you send to many request for some part of time. Tell what string did you get from google maps api with this 26th point?

Answer 2

Sounds like that software is using the Google Maps API v2, which has a limitation of 25 waypoints. The Google Maps API v3 has a limitation of 10 waypoints (start, end and 8 waypoints) which can be increased to 25 with a Business license.

Also, FYI the Google Maps API v2 is deprecated, and may stop working as early as May 2013.
