Ok, I began to play and I get some crashes. I change the compatibility of the launchers to XP SP2 and then it seems it works near half and hour and then crashes again. Now it crashes at few seconds of conecting.
The crashs says its a problem with the _Launcher.exe file related to a .dll of my Intel 945 graphic card.
I have windows 7, last drivers, windows 7 aceleration driver of intel...
