lost privilages to install?
 

Hi,
I've been using basic Limewire for awhile but recently have been having connection issues so I uninstalled the program and tried to re-install. But it gives me an error message saying the privilages to install this program have been lost on my computer. What is that all about?? I've spent so much time trying to get it fixed but no luck.. I'm so frustrated! I need to download music, I'm a total music junkie...!
I would greatly appreciate any help with this..
Thanks!
