I just updated to the new 4.1.158 today, and after re-starting, everthing is frozen when I tried to run any application, it will stalled. Even <Ctrl>+<Alt>+<Del> will not work! I cannot re-start it unless I turn the power completely off. Before this program update, it was working fine. My computer is Windows XP SP2, 2.8 GHz Pentium 4, 512 MB Ram. Need help!
