Is there something wrong with the games arcade?

I've just joined Major Geeks, and played some of the games.
Was playing Space Invaders (never thought I would see that game again - nice one...) and was getting a good score, when all of a sudden, the screen went black/green and I got the slogan SPACE INVADERS.'
Now, I know this happens if you allow them to get right down to the bottom, you lose your score and everything (this is how Iremember it, anyway).
Problem is, or was, in this case, the first row of invaders was nowhere near the bottom line, and I had two men left - no idea what happened?
So I quit the game, but then had this very odd message or something, saying that I had not logged on - only I had logged on. Have other players lost their scores like this?

 

Please look at this thread, most specifically post #3 and then reply in that thread with any issues you note so that it can be addressed.
Thanks!
