Thanks for your help. I´ll try to answer your questions one after the other: - No, I do not use a firewall. - With msnm I have the following trouble: on my office machine, I have installed the prog but can´t make the connection to msn. First I thought it was because I didn´t have Internet Explorer installed, so I did. Still didn´t work. On my home comp. Msnm works, but when I tried to play against Lebarronnn_90 the "check" button in the multiplayer menu wasn´t highlighted, so it couldn´t be clicked. Also we got no end of strange messages on the chat. Incidentally we were then able to play via IP connection proving the problem with the other players had not been on my side. - I looked up my IP on ipchicken.com and told my opponents to do likewise. This worked well on three occasions so I figure that wasn´t the problem.
