Cursor dissapears in every single game.

I just reinstalled the game on my computer yesterday, and since then every single game I joined, regardless of what game mode is it, my cursor would just disappear in the game. I already have this 5 minute queue thing before I can join matches now, due to the fast that I left too many matches, but how can I play when I have no idea where I'm clicking ? Turning on mouse trail doesn't help anything. My graphic card is nvidia gtx 550 ti.
