I updated to service pack 2 for winxp. Next thing, I could'nt open limewire. It turns out limewire uses sun/java runtime environment 2. Win xp service pack 2 takes out java re2 and uses their own virtual machine (big litigation going on with sun microsystems) which stops me from opening limewire. Now I took out sp2, paid 200 dollars for a pc repair man to fix pc and I get limewire to work. My question is I believe, in the future, that We will all need sp2. what is being done so that I can upgrade to sp2 without losing limewire again?
