Hi and welcome !
I made sure to read your post about 10 times...
I do not see any reference to you attempting to install LimeWire into a basic user account with no Admin rights...
(I assume that you have tried that and have simply omitted it from your explanation.)
And, this is not a crazy question... Have you tried installing any other Gnutella clients into a standard user account ? Phex would maybe be the best to test.
Last for now (and I am sure others will be joining in here soon), I assume that you are aware that it is an extremely bad idea to access any of the internet using an Admin rights account.
When you are connected to the internet through an Admin account you are far far more open to "Takeover" ! Your 'security is very much reduced.
Anyway... If the problem is a simple setting in your account(s), no problem...
If it is a Java issue you may be busy for a while.
p.s. When you install Java do you do it 'live' online or do you download the installer and then install from that file ? The latter is always preferable !
