This have a problem, I bought the X2 game yesterday, downloaded it, installed it today an now the server of linuxgamepublishing.com is down, so i cannot start the game because the LGP Security System Manager can't verify my key. So this system makes your licence dependant on the status of the lgp server. I expect this don't happens frecuently.
No announcement yet.
