download problems once and for all

[rapgame06]

Let me expalin a bit abour my computer first
3.06ghz processor
hyper threading
1024 memory
600gb (4 hard drives)
internet service provider tiscali
tested internet speed came up as 2010kbp/s-5000kbp/s
which is reasonable as i have 2mb broadband
download 506kbp/s a sec
reasonable
i have limewire pro(latest)

Now the problem
I have read all the above sticky and did all of that but i only receive 1kb/s-4kb/s.
Now i have heard that tiscali was the problem. i phones tiscali they said that its not them and that best chances are with your computer. I am a computer expert so i know all the fancy gadgets in xp service pack 2 and i have done that but now the maximum i receive is 8kb/s which give me the idea that its limewire itself. i have seen many froums unanswered when people say there downloads are slow. I would be really grateful if someone can help me out with limewire settings and what i should do from STEP 1 and how to do it. that way it can help me and other people. i have read the sticky and they dont make no difference to my computer except decrease my searches. if we still cant find the answer then i will fax limewire once and for all to find the problem and i will write the solution here.
