2.57b crashes after opening User Preferences

Hi,

i am using Blender 2.57b with my HP Probook Laptop, 3GB ram and Windows 7 home premium. When i click User Preferences, the program crashes so i have never seen what it looks like, it doesn’t even open. Any suggestion ? Thanks,

Victor

In the bottom left corner of the 3d view change the window type to User Preferences.
