Error: "The memory could not be 'read' " while trying to start waypoint work Options

[NightHawk]

I have RCBot2 installed on a dedicated Windows XP SP3 based TF2 server for now.

I am using RCBot2_051_Beta

The server shows:
version
Protocol version 15
Exe version 1.0.7.0 (tf)
Exe build: 17:01:11 Sep 14 2009 (3964) (440)

The server starts without issue and I can play with the bots in a map.

However, I am wanting to play with setting up waypoints for maps and get familiar with this.
So, I load the plugin and no errors are reported.

I am following the steps in the thread
"Tutorials: Waypointing for RCBot2 - Team Fortress 2"

I load a map and then type the following two commands:
* rcbotd waypoint on
(no issue here)

But when I type this command:
* rcbotd pathwaypoint on

I get an application error

---------------------------
srcds.exe - Application Error
---------------------------
The instruction at "0x010d1328" referenced memory at "0x19302d34". The memory could not be "read".


Click on OK to terminate the program
---------------------------
OK
---------------------------

Maybe I searched on the wrong keywords or I am missing this in someway - but I am not finding anything on this. Any ideas why this is happening?

What else might you need to troubleshoot this error?
