Common Problems:

• The game does not start - it immediately says "Illegal Memory Address"
  There are several possible solutions to this:
  • Extract the game from the zip file before running it.
  • Run the game as an administrator.
  • Add the game to the Windows DEP exclusion list: http://www.windowsanswers.net/articles/dep-config
  
  
• The game loads, then crashes with the message "Player nation is not in nations.list file"
  The player_nation in gameoptions.ini is invalid. Ensure the country name is spelled correctly and capitalised correctly. The nation you are trying to play may not be in the game yet - check the 'Playable nations" list.
  
  
• The game loads, then crashes with the message "No suitable starting port found"
  The selected player_nation in gameoptions.ini is landlocked or does not have any ports in the game yet, so it is not playable. Please select a different nation.
  
  
• The game crashes on startup with no error message or the graphics do not display properly
  Disable OpenGL by changing "OpenGL_graphics = 1" to "OpenGL_graphics = 0" (without quotation marks) in gameoptions.ini
  
  
• I use a non-QWERTY keyboard and the controls don't work
  There are instructions for changing key bindings in the guide.txt file. If anyone makes a good keybindings.ini for AZERTY, QWERTZ or any other common keyboard types feel free to post it!
  
  
• The game runs very slowly
  There are several ways to increase performance. The following settings are all found in gameoptions.ini:
  • Lower the number of ships and aircraft in the world.
  • Change the fire rendering style to 2.
  • Change the radar model to 1.
  • Set realistic_UI to 0 (this makes the game a lot uglier and is not recommended)
  • Enable OpenGL in gameoptions.ini, if it has been disabled.
  
  
• I have been given a mission which is impossible to complete!
  1. Download this: http://goo.gl/QsUsqE
  2. Put MissionCompleter.exe in your game folder (the same folder as the Sub Commander exe file)
  3. Save your game.
  4. Run the Mission Completer (it should say "Mission complete!")
  5. Load your game. The old mission will have been completely forgotten and you will be quickly given a new one.

Known bugs in current version:

• If an unconscious crewman dies while another crewman is attempting to revive him, the crewman who was trying to help will keep trying to revive the body forever. You can stop him by ordering him to abandon his post then ordering him to return to duty.
• Sometimes your country will accidentally nuke itself, then declare war on itself. This will turn every friendly ship and port hostile to you, so you're basically screwed... such is life in a nuclear war (I'll fix this soon)

If you have a problem which is not listed here please post it in this thread!
