Good help, and i would add that you have to add collanos in the firewall exceptions because it's not auto

cheers

I found the same problems but with Gil we have found a solution.

I am using a DIGICOM 3c router,
I open the port 9701 in the NAT (Sua Only settings) and now it works as it should.

now i can share files bigger than 200kb, so i guess all of you are having problems in file replication you have to open that port in your router!

Have fun:)
