Your system needs time to download the item list to the database for CMP or CM2.
The other way is to go directly to the DLS using yor internet browser. Login to the DLS using your username and password that you created up on Planet Auran. This is the same username and password that CMP/CM2 uses to download assets off the DLS.
The DLS is divided into categories. Pick one that you're interested in, and explore to your heart's conetent. If you feel like downloading something, click on the download now button. CMP will pop up if it isn't loaded already, and you'll be able to download the item from the DLS to your PC. Make usre you have the auto-commit option renabled. This will make sure that the assets are loaded into Trainz so you don't need to do this manually.
I'm sure other's here will be able to add more or less to this.
