This happens to me too , its gotta be something on the network or something because no P2P program works and i just get unstable connections for all of them. I reformated a computer completely to just stock windowsXP home edition first thing i did was download and install LimeWire does the same thing. Configured my router as much as i possibly know and still nothing. I used to use P2Ps for years and now i just get an unstable connection which i cannot even search with, let alone download anything.
