after update kde does not start

After updating my Suse 11 64 I get an error that kdeinit4 cannot be started after I login. If I login as safe I can run kdeinit4, but I don’t know how to get back to normal (KDE4) Any ideas?

do you have kde3.5 or any other desktop installed ?
if so rename the .kde4 directory and then log back into kde4 it will reset your desktop to default
