Help! system can't boot after upgrading to bash-2.x

["Luan L. Tran" <lltran students wisc edu>]

Dear users,

I'm using RH5 and after upgrading my bash-1.47-x to bash-2.x  from redhat ftp site, my system cannot boot :(  What should I do?  Here are the error messages when the system loads:

While opening UTMP file: no such file or directory (this line repeats many times)
Init: Id "1" respawning too fast: disabled for 5 mins (the # 1 will change to 2,then to 3)
Init: no more processes left in this runlevel

when I tried to ctrl-alt-del, it said:

Shutdown:  warning: cannot open /var/run/shutdown.pid
Init:  cannot execute "/etc/rc.d/rc"

Please help me!  I don't want to reinstall everything over.   :(  TIA
