Hi...
You haven't included any info on your setup yet but, in the interest of trying to speed things up for you, first try looking at- - -
http://www.gnutellaforums.com/showth...and+install%2A
If that doesn't help you, than try a 'search' starting with...
limewire and java and install*
...as your search 'argument' to enter.
From reading numerous other posts on this same subject, it is probable to presume that you need to install a different 'Runtime Environment'...
Don't worry, others will also certainly respond to you...
