System.NullReferenceException Error Message

[racer043]

Hello,

I am getting a System.NullReferenceException message every time I start this one particular activity on a route resulting in Open Rails crashing to desktop. Being new to MSTS/OR, I have no clue what this means and would greatly appreciate some help.

Have also attached below the most recent Open Rails log in a zip file.

Thanks.
