Strange ns-allinone-2.1b5a.tar.gz Results

[Lukas Ruf <lpruf@stud.ee.ethz.ch>]

Hi there,

I recently executed the example.tcl in ns-allinone-2.1b5/ns-2.1b5 by 
	ns example.tcl
Things worked quite fine, i.e. no problems.
But when I wanted to see the results by
	nam out.tr
something really strange to me happened:

ns-2.1b5> nam out.tr
You are using the tracefile format older than 1.0a5
which will not allow you to run namgraph
nam: badly formatted event at offset 39 in out.tr
nam: `+ 0 0 1 tcp 1000 ------- 1 0.0 1.0 0 0'
ns-2.1b5> 

Does anyone know, what I did wrong ? I fetched 
	ns-allinone-2.1b5a.tar.gz with 15393142 Bytes 
on Monday last. The installation and the validation run without
problems.

Any help would be gratefully appreciated.

cheers,
Lukas
