South Devon banks v1.4 problem

[deltic009]

I'm sorry if this fault is covered else where, but if I try and look at Plymouth on the overhead map, it just crashes out with the old RailProc error every time. This happens on a scenario I set to start at Plymouth, and one that ran all the way from Totnes faultlessly.
*UPDATE* It also happens at Exeter, as soon as I press F3 to bring up the HUD, or 9 to look at the map, RailProc error again. It's a great pity, as this looks like a very superb route.
