my system won't work with it either. I used to be able to run the  
i386 version on
my amd 64fx2 but this also crashes with no error messages, just a  
lock up after
a while, seeming to be due to disk access. I can't get anywhere at  
all with the
64 bit version on this machine. I am trying the same 20070328 and a  
of prior versions also.
