•	The game may not be able to start.
•	Slow game performance or your mouse may move very slowly when navigating in-game.
•	Game may appear to stop responding (freeze or "hang") when a single game screen (such as the Star Systems or Orbital View screen) is displayed for several minutes.
•	Your screen may go black.
•	When you play a multiplayer game, you may experience slow performance in your game (lag).
•	Your game may run but you cannot shut down the game and restart the game multiple times without a restart.
