Ah. That was the missing component. I didn't realize you had to have already launched the ship before activating the trainer. Also, would it be possible in future iterations to increase the "infinite credits" to $9,999,999 (or, even better, $99,999,999 [I know the game seems to take anything over 9,000,000 and turn it into scientific code, for some reason, but it'll still allow you to have that much]). The current amount of $999,999 doesn't allow you to buy tier 5 items as they all cost $1,000,000 or more.
