impossible to download torrents on new macbookpro

[tomcut]

Hy everyone

Just bought the new macbookpro and the torrents I launch on Bittorrent

don't start to download, they stay at 0% for days and that's it.

The message on the low right-side of the windows stays on

"checking for firewall...".

I know it is not a problem of the torrents cause the same torrents works

very well when launched trough an older mac.

What is the problem?

Thanks!
