Actually, that looks pretty similar to most social science networks :-)

The screen shot seems to show that optimization process is going fairly 
well, the 'energy' is generally decreasing so the positions are probably 
converging on a "good" layout.  If you want it to try going a little 
longer, you can adjust the "max passes" parameter to something higher 
(perhaps 2000)  to give it a little more time to reach the min epsilon 
energy threshold. Or, if it looks good, you can leave it where it is.

This page gives more explanation of the various parameters for the KK 
layout:

I'm afraid I don't have enough information to make a suggestion (and I 
don't have a windows 7 machine for testing anymore).  Did it print any 
error messages in the log window?   If you are comfortable starting the 
program from the command line (windows console C: prompt), it may be 
able to print out an error to the console which might give us something 
more to work with.
