Hey everyone.

I've been trying to download the rest of the dependencies for Donner Pass, but some of them won't download.

I saw in my copy of Trainz Simulator 12 (in-game) that they're all part of dependencies that need to be updated.

Any ideas?
This is probably all part of the server screw up that is affecting downloads since the 22nd Jan.

You could try using the dls and view the asset history if you do not see an earlier version in the hits, then download that via FTP and import the cdp's into your game.
