Whats this got to do with the OP's moan about new versions? I just can't see the link? Why should a new version route work on a old version Trainz software? It's like moaning about paint 3d not working on Windows XP (which some of the luddites on here think is the bee's knee's!) :'(

Except that this is a case of files that won't load into the same version, with only a service pack in between. As long as the product is simply called Trainz: A New Era users are going to assume it's the same software. That's about like having Word 2.01 files that won't load into Word 2.0. The convention is normally that with a major change like that you have a new version number for the software. (And even then there used to be the option to Save As in the earlier format.) But then, who these days even remembers version numbers?
