I have a simple question, but i causing me not to sleep.

I would like to begin to modify the look of my site.

ANY time I change ANYTHING on site_html.pl get the following popup when i try to build :

"Opening nph-build.cgi using WB32.exe"
It then ask me if i want to open the fil eof download it.

As a result I can not change anything on my site.

I know if I can just get tpast this , I will have rather smooth sailing.

Please help me.
