only one torrent uploading at a time

[togarha]

Hi!

I have utorrent at university computer. I know that it filters the information, but I encript the protocol and it seems to work more or less fine. But the problem it that only one torrent is uploading. I am downloading some torrents at a time, but it only has one torrent uploading.

What is the problem and how can I try to solve it?

Thanks in advance...
