Cannot Login After Using Kuser to setup Accounts

[amcinroy]

I have FreeBSD 4.10 installed. Everything was fine till I ran kuser and
rebooted. It said my root password was incorrect even though I hadn't
changed it! I followed the advice I read on one of your posts. The backup
passwd file didn't help. Also when I tried to change to default passwd file,
I received the message that src wasn't a directory. I manually went to
/usr/src it is indeed there but I can't cd to it! Help!
