Problem with an activity on New Forest V2

I have received the following set of messages when attempting the an activity on New Forest V2 (Watersnake):-

I would be very grateful if anyone can advise how this can be resolved?

PS I had a similar message on a Steyning activity.

Hi Alec,
If I remember correctly, I think this is down to the Tsection.dat?

This can happen when the name of a location is changed.

Go into the editor stops section and untick the entry for Sway Up.
Exit the editor and save.
Reload the activity and retick the stop which should now show the correct name.

Save and the error should be gone.

Right then Ian.

Did what you said but couldn't untick Sway because none of the stations were ticked!
I therefore ticked all of the stations because the "readme" said that the train did stop at all stops, and then clicked on recalculate because they all said 0.00 arrival, etc. Lo and behold it worked!

Once again my head aches!

Thank you, Alec
