General query related to New Forest V2

When installing New Forest V2 (Watersnake) I ran the "Check Route" routine in Route Riter - as I always do unless the author states not to. I was offered the opportunity to substitute summer texture for winter texture and I said "Yes to all". It continued to do its thing but then threw up a series of error messages as illustrated below:-

This seemed to apply to numerous files and I clicked OK every time. When this was complete the route appeared to be working as witnessed by my query on one of the activities in that area of TSSH.

Obviously I would welcome some general comments on what this means, because I can imagine some simmers may be put off by this. It is obviously related to winter and snow, but more than that . . .

Alec,
Not sure if you have done this or not; but have you tried a reinstall of the route to overwrite any existing files and to install any possible missing files?
Cheers

Thanks for the reply, and yes I did reinstall, etc. My own limited understanding is that no snow textures have been provided, but of course I may be wrong? However I would appreciate somebody giving a clearer description of this, as it does happen in several other routes.
