As your profile is "Private" I have no idea how long you've had TS so will go through it step by step.
1. When you have subscribed to one, go to, Drive, Workshop tabs to complete the download.
2. When scenario shows in the list, click it. This will list all the assets needed bottom right.
3. Any assets you own will be in "Light type", any needed will be in "Bold type".
4. If the "Drive" button at the bottom is in Bold type then it is active. If in Light type then it is not. It's very hit and miss, sometimes works but mostly not. If it doesn't wotk then play the scenario from the "Drive, Standard" tabs.

If you are missing some assets and stil want to play it then when you load the scenario a box will appear with "Edit & Exit" in it.
Press F2 then Yes and it will run unless it's the P train bits that are missing. If the P train is there, then all you will be missing some AI traffic.

Hope this helps.

I followed your detailed instructions but... no result.
At the point 3 of your instructions no asset seems to be missing, but the Drive button is in Light type.
I went into the Drive, Standard option and the route I subscribed there is not.
In the QuickDrive tab I found some WS routes I unsubscribed that work perfectly, but the route I search is not there.
In the folder Content/Routes I found the folder of the route we are talking about (Great Eastern Mainline to Swindon...). In subfolder Scenarios there is a QuickDrive folder.
Some help?

Are you looking for the correct route name? It's the Great WESTERN Main Line to Swindon, not EASTERN.

Yes the name is what you say. I'm sorry, but the result is the same.
The GWML to Swindon doesn't appear in any of the other Drive tab only in the tab Workshop, where the button Drive is grayed.
Examining the Content/Route folder of this route I found a scenario that is much like to a QuickDrive scenario.
So another question. Why in the QuickDrive section there is only the New York New Haven route? Where are all the routes that allow this option?

Workshop routes usually only come with QD scenarios.
In QD maybe you should select a different loco type (say pick a diesel which can run on any track) then see if the route shows up.

I want to say thank you for this help, I have several senarios in Drve,Standard that I can find and run. These would'nt drive from the workshop screen.
