hello, i also had the same problem..
my LW as the admin account is only connecting one green bar out of five...
and it connects fine on my brother's account <which is on the same computer>..
iv been reading a lot of threads about this issue..
not just here but some other sources...
iv been trying all the suggestions...
including the disabling of firewall..and even uninstalling firewall and limewire...then reinstall it...but to no avail...

Finally..only SKIER889 who gave the BEST solution to have my LW worked again...
Like he said go to: C/Documents and Setting/"User (whichever one ur logged in as)"/application data/limewire (this was the problem folder for me,...)
I just quite LW after deleting the LW folder from the application data and just restarted it...then it'll ask for the settings again...

Im so glad after following what SKIER889 said my LW works again better than before!!
now iv got 5 green bars on my LW...!
Try it guyz!!....it really works!!!

Thanks, SKIER889!!! you're a genious!! (^_^)
