[font color = blue]"I set the Configuration Control so my Baron always loads cold and dark, but now either I cannot start the engines, or the engine ignition switch starts flipping from left to right very fast. Is there a fix for this?"[/font color = blue]

Yes, read manual section 3. When starting cold and dark, you first need to remove the tie downs and put the pilot in the cockpit using the Configuration Control. Once you do this there will be no problem starting the engines. ;-)
