Well, now I have downloaded the route but now there is a new problem, the route has no textures or elevation changes, this problem always happens on routes made in TRS2004 or 2006.

You need to open the route in TS12 or T:ANE make a slight change like moving a tree and then saving the route. This will upgrade the route to a newer version that can be imported into TRS2019.
On the other issue regarding unknown asset. This has to do with a category problem that occurred with a bunch of things uploaded to the DLS at one point. Routes, sessions, and other assets were either marked as miscellaneous, or unknown.
