dodgec,
you have 2 firewalls running -- this causes problems and reduces your computer security -- disable your windows xp firewall -- see if you can connect now -- if not try those fixes again -- if still no good try an older version of LW from
here (try version 4.12.6 -- download
java 1.5.0_11/offline version to use with that version of LW) (JRE 5.0 UPDATE 11) -- dont forget to remove all your other versions of JAVA from your add/remove program --
Start --> Control panel --> Add or Remove programs
