As you have TANE Deluxe and TRS19 to install the required routes, the only other assets were in a file linked to my Google drive. No visits to forums required. I even included instruction on how to get the few assets that turned third party from the DLS due to build numbers etc. You shouldn't have any missing assets if all those are installed. With the sessions, all external assets are linked to origin on the launch page.
