I'm not using xfire (never heard of it)

and "repair" is always the first thing i try when i get knocked offline...but it never works, even before i started having the limewire problem whenever i click "repair" it always says cannot clear ARP Cache...that started after i installed the latest msn messenger...
also i recently downloaded morpheus...and it does the same thing limewire does....but imesh, winmx, and warez p2p...don't give me any problems
