Help with "need more sources"

[Big Friendly Git]

I've been using Limewire for quite a while both at home and at uni. Recently though at uni Limewire has had trouble connecting to the network (though it seems to be OK the past couple of days) and when it does manage to connect every (or almost) download reports that it needs more sources (the few that do download do so at about 1KBps). I have Sygate firewall ,though its configered to allow Limewire and works fine at home - which is also on a LAN - adhoc connection I think, so I don't think its that and I've got Limewire set up to allow 50 simultanious downloads using all of the bandwith (it can download 5MB it under 10secs so bandwith isn't the problem either). Since the company that supplys the LAN doesn't like us using P2P (and disconnect you if you use it after one warning) I think they've got a new firewall up thats blocking it or something similar (they have actualy caught me using Limewire before BTW) .

So what I want to know is does anyone know what is going on and a way around it. I was thinking about getting a porxy though I don't really know much about them and don't really know if that would work.

Thanks for reading,
