Hi SAM,

I just installed Nmap 5.61TEST4 in Windows but can't reproduce the error
your seeing.
The error your seeing indicates that the script can't load the url.lua
library which sounds strange.
Have you tried re-installing and see if that makes a difference?

In regards to writing your own scripts, the tutorials and book is probably
the best way to start.
If you've already written a few scripts, submit them to this list and we'll
make sure to give you some feedback.

Cheers,
Patrik
