What you wrote about the hyperdrive is strange (I double checked and everything works correctly); if you try to hack the hyperdrive after you walked through the first nightmare successfully you should get the message: "You don't understand much about hyperdrive settings. Something needs to be done about it." Then you have to do one more thing to hack the hyperdrive.
Whoops sorry, I replayed and it actually said: "you remember your COMPUTER settings password". So remove "settings" from this text, people often get the relevant information and ignore the rest, I saw settings so I thought hyperdrive. So I got to the end ( I say that because the name of the game and the credits appeared on the screen and "end" so probably the end)
