I had this problem in ns-2.33 after installing and therefore installed ns-2.34 to see if it rectified, I installed each version following the instructions from
http://www.edaboard.com/ftopic297674.html and validated each installation which came back successful.
If anyone has any ideas please help me as I have no idea what is wrong.
