On the score, that's a known issue with STTNG. It can't keep track of the numbers that high while playing (not that I've ever had that problem) and I believe scores above 10 billion go to the Q Continuum list, rather than the regular high scores. See if it registered there.
Found this: The real STTNG has multiple issues with high scores. For one thing, scores over ten billion are well within the realm of possibility, but the score when shown in game doesn't show the ten-billions digit, so players may think their score has reset. the game DOES keep track of the score properly, though. when it displays the Grand Champion score during attract mode, it shows the full, correct score (which on mine is about 22 billion). However, there are other problems: there are four different high score lists -- there's the Grand Champion, the Honor Roll (for players with no buy-ins), Officer's Club (for one or more buy-ins), and Q Continuum (for scores above ten billion, with any number of buy-ins). Unfortunately, scores over 10 billion are ignored completely by the Honor Roll and Officer's Club, and will only register on either the Q Continuum or for Grand Champion.
