this firefighter needs help. I havent had ploblems connecting to limewire until about a month ago. how I use to connect is first go to microsoft securities center and go to internet options then move the securitie level to low and lime wire would connect. Something happened, now when i try to move the slider down to low i get an error message {the recomended security level for this zone is medium} It wont allow me to change settings below medium. you all are the experts could it be something else?

xp
norton internet security
