Well, I'm afraid I can't help you with the settings, since that is a personal touch you want to apply.
If it happens again, please upload the config file (the .py version of one of the two files I mentioned before).
Also, about the -TestMode, make sure you put a space between STBC.exe and -TestMode (if it ends in a " then you need to put a space between that, so it becomes STBC.exe" -TestMode). And you _must_ spell it exactly (case and all) as -TestMode and you must start the game the game through the altered shortcut. 
Further more, if you don't have an US keyboard (or US layout) then it might be another key, namely multiply (numpad or otherwise). Otherwise it's the "backquote" as it's also called.
