OKAY..for stupid people like ME!!! I have done EVERYTHING and nothing has worked until I did sort of what that expert suggested. On VISTA START.. I clicked on my name that is on top of right side..APP DATA appeared in a list..CLICK and you'll either see yellow folders or a list of folders..look for the limewire one and delete it...restart and be in shock because it's the only thing that allowed me to see the 4 green bars..THANK YOU GRANDPA!!!!
