OK, I've used LimeWire successfully with both Verizon DSL & Comcast Cable. I've also used it successfully after reformatting my computer. Well, I reformatted my computer last week & got reconnected with Comcast Cable. Now, when I try to download a song nothing happens. There is also a warning at the top of the page saying that files that don't have a lock are not official LimeWire communication which never happened before. Can anyone help me? Please?????????/
