Hey Nahblebnik,
Have you already tried verifying your gamefiles?

• Select Tropico 6 from your Steam library
  
• Either right click the game in your Library, or click the gear icon from the game's Library page on the far right.
  
• From the drop down menu, select "Properties..."
  
• Select the "Local Files" tab and click the "Verify integrity of game files..." button
  
• Steam will verify the game's files - this process may take several minutes.)

In case this doesn't solve the issue, please reach out to our support at support@kalypsomedia.com with a description of the issue, a DxDiag.txt and a crash dump attached if available, so they can investigate. Please also include wether you are using mods.

• Save the file as "dxdiag.txt”
