So i have recently gotten into KSP and i am having a issue with getting KOS to work. "The parser used by kos is complaining about a part of the script it can't understand. KOS uses a parser-generator tool known as TinyPG, and the text description you see from this error message comes mostly from TinyPG, not from KOS itself". This is what comes up whenever i try to run anything in the terminal. What should i do to fix this?
