Problems with Launching the game:
First of all manually uninstall anything Graphics Card related (Intel, nVidia and AMD) using Windows Control Panel -> Program and Features.
Once uninstalled, restart your system then install the latest drivers, making sure the latest version was successfully installed. These drivers can be found via the Graphics Card Drivers website:
Intel – https://downloadcenter.intel.com
Nvidia – http://www.nvidia.com/Download/index.aspx?lang=en-us
AMD - http://support.amd.com/en-us/download
Once this is done, check your system manufacturers’ website to make sure you have the latest drivers available for your system.
Once this process is complete, use Windows Update to check and make sure there are no outstanding updates available for your system.
Then try to run the game. If you're still having issues please create a thread within our technical issues/crashes PC sub forum which can be found here - https://community.sigames.com/forum/513-crashes-and-technical-issues-on-pc/
Problems with Saving the game
If you already have a save game, can you try right clicking your save file, and click properties.
Then see if there is an 'unblock' button. If so, please click it, then click OK and try loading the save. Once you've done this, go to FM -> Save As and save the game with a different file name to see if it will save correctly.
If not, can you go to the security tab, then click Edit, click on your username in the list, and in the bottom area select 'Full Control', the OK and OK again.
We also recommend doing this for the save games folder. Again right-click on the folder and go to 'Properties' and make the above changes to the security tab.
Then try loading the save and again go to FM -> Save As and save the game with a different file name to see if it will save correctly.
