Mouse wont appear, help!

System

Hey, I finally got the open beta loaded and I started up the game, only to find that my mouse cursor does not appear nor does it work. Ive moved it around the screen thinking it might be invisible, but it simply isnt working. I notice that it will appear on the edge of my second monitor (im using dual monitors) when I move it all the way to the right, but it cant go past the edge. When I move it back, it dissappears again. Can anyone help me?
