I installed another laptop
with Win XP Pro SP3. I got the plugin up and running in 5 minutes. Encouraging, but frustrating at the same time.
I read the thread you mentioned in post 2 and followed the same steps as Helmsmatt at the very beginning of my investigations. Basically, it is about defining rules or exceptions in the firewall. On top of that, there are many differences between the home and pro editions of win7 in regard to networking.
I would like to identify what is blocking the communication but I miss background information on the plugin itself. Is it using only UDP protocol ?
I think it could be valuable for other users to get the right config on win7....
Thanks for your support
