Help Please. Can't remove old Limewire & install new version

[wnitschkeh]

I have no clue what to do anymore. I can't delete any of limewire in my hard drive because they say it's being used. I can't download any version of the limewire now. I don't know what I'm doing and I don't understand where to go from here. I don't have any icons, it's not in my add of remove programs, I don't know where to look and how to get this fixed. When I bought the limewire system it sent me to the members area. Was this a third party or was it the offical site. I need some answers and maybe someone to hold my hand to help me. PLEASE.
