Quite odd. Assuming you didn't change any settings on your PC (or Windows didn't change them for you - convenient when it does that, eh?), then I would probably conclude that you are on a streak of bad luck (ha- right) or your ISP is cencoring your connection. They might be trying to block your downloads when using <i>any</i> file-sharing utility. Are you sure you didn't change anything in your software, hardware configuration?
