I dont know if this helps but I've also realised that the connection in the bottom left of the screen is always on one bar. Also, I managed to find my windows firewall settings, and limewire is already in the exceptions list so that's definitely not what's causing the problem! And when I knocked off the windows firewall for a few mins, a warning came up saying that there was no firewall protecting my computer, so i don't see how there could be a firewall?? But there must be because the brick is still in front of the globe. It's so confusing!!
