Celtic Trainsim

Hope someone can help.  Some of the "train" downloads on the 'celtic trainsim' website fail to load the plug-in which creates irregularities in playing some of the routes.  I don't know why and I don't remember having this problem before.  The attached screenshot should highlight the problem.  Not all the 'train' downloads have this problem.

All of the trains offered for download have been working with no complaints for three years or more. The route shown (Kilmagranny) is five years old.
I only have an old (ish) sim version  1.7.1.8   as I'm not actively developing any content now, or for the forseeable future. I just loaded Kilmagranny route using 29000 unit and as the above pic shows it works fine with that.

This has been mentioned before.
Please use the 32-bit version of OpenBVE to run the problematic units.

(It was an oversight when I originally built the plugin for these trains many years ago)

Stephen Cross just told me all's well using v1.8.2.0
Chris, I've been thankful for your plug-in since the day you built it, it's done my trains proud! Would never have had the authentic CAWS implementation without it.

My thanks to both 'Graymac' and 'Leezer' for their help.  I have now managed to download the trains on Celtic Trainsim with no problems using an older version of BVE '1.7.1.8'.
