1. Unsubscribe from all mods.

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

4. 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”.

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

6. Install the game again.

4. Install the game again (using the latest distributive from our official web site) and surely run the distribution kit with administrator privileges (right click on it and choose "Run as administrator" in the context menu). During the installation process, you should agree on installing all additional software, because it's necessary for correct program operation.
