problem with ET..

Hello,

Yesterday I tryed playing but I had the same problem over and over again and still today.. and it wont allow me to play!

So to problem is like that: I connect to a server, it loads the map, and no matter what I click (if its mouse1 or join axis\allies) the game suddenly freeze and the a windows pops up and says ET.exe isnt working good and I need to close the application.

Any of you had this problem or know how can I solve it?
Appreciate any help!
