ksmserver problem in f12 snap1

Fri Sep 4 20:38:22 UTC 2009

I am trying to install f12-snap 1 and I get a message stating 
"could not start ksmserver" and then the CD just hangs, so I am 
unable to get logged in to run the install program. Also, when I 
click "ok", I am returned to kdm and the username is liveuser, 
but the password field is blank and there is no indication of 
what the password is (leaving blank, using liveuser don't work).

How can I install this?
