The latest is 0.10.7; some platforms might not have the latest version 
in binary form, so the one available for those platforms might be older, 
e.g. 0.10.4.

You might want to try 0.10.7, if you can.

What file formats are the input files?  Read the file into Ethereal, 
select "Summary" from the "Statistics" file, and report what it says for 
"Format:".

I assume you didn't specify a "-F" flag, so the output file was in 
libpcap format.
