Hey, nice to see more people from PR here.
I got the same problem with Liberty, here in Manatí. Was using Shareaza for Gnutella and my downloads, which here usually at 24 kbps fell to < 1 kbps.
And worse: it looks like they are throttling other networks as well. I also use eMule and I usually leave it the whole night connected, but now in the morning, for weeks, it has downloaded almost nothing.
I`m downloading Ares right now. Hope it brings some light to the problem.
Thanks for the info!
