Unless I am misunderstanding the issue, I have the same issue, my issue is with content manager, it does not want to "hook up" to the DLS. In TANE, I can for instance, download a
given asset, such as a route, and content manager will download all of the dependencies that are available on the DLS. Another nice feature is if I would say download a route from a
3rd party site and that route uses a lot of DLS content, I can get content manager to download all of that content by simply clicking download once I have imported that route. That
does not work in TMR2017 for some very strange reason. I should in theory, be able to take an asset from TANE, import it into TMR2017 and then download and all of the dependencies
should download. Instead my browser begins hunting and after a long time I get an error message saying Trainz is unable to communicate with the DLS. I've triple checked my login, it
is OK, and I am quite sure that TMR has access to the internet, because I downloaded it from NV3, and it is constantly trying to get me to purchase the latest add-on content when I
launch the game. I am a little put out with this, I bought the game during the recent sale. Maybe that is why it was on sale, it doesn't have all the features?
