Hey Ratna, I have the EXACT same thing happening. I too have 10.3.9 and I'm on LimeWire 4.10.9. Everything is slow, LimeWire only downloads at 1-4kb when I have a 1200 Kbps DSL connection.

Not only that, even when it downloads just one file at 1-2 kbps it still ties up most of my bandwidth and I am literally unable to do anything else. Worse yet, even when I quit LimeWire, it still holds up traffic. The only thing I can do is unplug my modem and plug it back. This resets whatever is tying up bandwidth. This only happens with LimeWire. I can use other programs to download files (such as Speed Download) and this doesn't happen anywhere else.

I am very frustrated because LimeWire at this point is useless to me .
