Ok, here's the deal:
Yesterday, I've downloaded LimeWire and couldn't connect... Later, I've been to this forum and readed all the "sticky" ones, and the 6346 config worked... for a while. I got like 20 minutes connected and then it never got connected again =/

I've did all of those things listed, and none got results again. I've called my ISP and they told me that there's no firewall on my PC.
As you can see, I'm desperate xP... So could ANYONE OUT THERE help me please? xD Thx.

Oh, almost forgot... Windows XP with (f**king) SP2, and I've disabled the intern firewall too.
