I am not sure what happened, since last time I use it. Could you help me? I attached the error message below. Thank you for helping.

Try sysctl kern.sysv in a terminal window.  This will show you the 
current values known to the OS.  You may need to set a larger value to 
shmmax than it currently has.  After you modify /etc/sysctl.conf you 
must reboot the computer to get the values into use by the OS.  Check 
them again with the sysctl command.


          kern.sysv.shmmax=10485760
          kern.sysv.shmmin=1
          kern.sysv.shmmni=32
          kern.sysv.shmseg=8
          kern.sysv.shmall=4096


You may need 16777216 instead.  You do have a large display!
