I very recently bought City Car Driving but when I install vehicle mods from the workshop they do not show up in-game. My game version is 1.5.9.2 (build 27506)

I tried following instructions from other discussions but they did not work.

What I have tried:

1. Turn off the Steam cloud profile synchronization for City Car Driving – open your Steam client, click on City Car Driving with right mouse button and choose “Properties” from the context menu. Then open the tab “Updates” and there turn off the option “Enable Steam Cloud synchronization for City Car Driving”.

2. Uninstall the game in Steam.

3. Manually delete the folder, where the game has been installed (it will remain after uninstallation) – …\Steam\SteamApps\common\City Car Driving

3. Delete the folder "Forward Development" from your "My Documents" folder.

4. Install the game in Steam again.

Also I have tried to create a new profile.
