Hi there! Just wondering if anyone can help me?

I just bought a Mac pro and am running OSX 10.4.10
I then bought Limewire Pro 4.14.8 and it was working fine. Then for an unrelated reason i shut down my computer and since then i cant download anything. Its on 'Turbo cgarged connection' and i can search for stuff but just cant download, Everything says 'Need more sources'.

I tried following the advice of 'Lord of the rings' (thanks for that!) from previous posts but the only option i have available to me in 'tools' is 'Advanced' and then 'Statsitics'.

I did click in the pop ups 'revert to default', and then i hit 'ok'. Should i have clicked 'restore Defaults' instead?

Many thanks for your help in advance! : )
