Ah-ha I got it all figured out now... it's okay thx for caring though. After a little bit of research I discovered it's not yet ready to played in SP mode but I do online and it works fine!
But why is there only one ranked server? And every time I check there's always less than 3 people playing on it... seems a bit odd to me when there's like 10 other servers which are so popular but all they run is space maps... Thos get really boring after a while and there seems to be no point.
It's true.
