Was wondering if someone could help please??

I have downloaded Limewire as per instructions and have just recently upgraded to the latest version but I still have the brick wall in front of planet earth and I just don't seem to be getting the results from my searches also, my download speed is very slow. What can I do to fix this?? I have tried what they say on the Limewire help pages but it either does'nt seem to help or I get lost with what they ask me to do!! perhaps I am being stupid but don't know what else to do!!??

Thanks in advance
