utorrent connection red

[pnpprob]

Hello,

Just a quick question. I ran utorrent 1.6 on my old computer with no probs since upgrading to a new computer and vista, nothing but trouble with unable to map to pnp. I've tried a number of things: Port forwarding, firewall changes. I've finally got it downloading nicely, however my connection goes from yelow to red and says no connection, yet is going along nicely. Should I worry and continue to try and fix, or is it a prob with vista, seeing as it appears to downloading/uploading nicely.
