Netrender - network renderer for Blender

Hi,
I wanted to make myself a small renderfarm between 2 computers and i found that blender (2.69 at this time) has an addon called netrenderer witch can be found on the addons menu - user preferences. This is great that we can make renderfarms.

saw the tutorials http://vimeo.com/59130318, read the wiki http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Performance/Netrender, but i have just a little problem ( a big one since i cannot make myself the renderfarm)

i get this error when i click on the master -> Start Service, and cannot go any further because of this. Please help!
“[WinError 10013] An attempt was made to access a socket in a way forbidden by its access permission”


ps: i even got the firewall off, but still no luck

You probably have figured it out by now, but I had the same problem today and what I had to do eventually was to change the default Address and port. I used “localhost” and “8080”.
