Limewire Running Extremely Slow/Freezing Up

[bluegrass1dcr1]

To answer the basic questions:
I'm on windows 98SE
No firewall that I'm aware of
63 MB of ram
I couldn't find an amount for hard disk space
I have a cable broadband connection through a Belkin wireless USB network adapter and Belkin wireless G router set up at the house here
Newest LW version
ISP is Insight Communications
Test page worked
Not my first time using LM but is first time with this PC
And I live in the USA

Everytime I start up LW it runs extremely slow and then freezes up.Do I not have enough RAM or something?
