Link with My Trainz account
Have you linked your game with your My Trainz account? This is done in the T:ANE startup menu under trainz settings. Once the Trainz Settings window pops up, click on the internet tab and type in your My Trainz username and password. One log in is complete, start game and you should see a whole bunch of stuff in the download menu. You will probably want a First Class Ticket for your account (YAY micro-transaction!) to speed things up, I had issues with download time out prior to getting FCT.
