I to had McAfee on my show machine. It was interfearing with Hoster. So i took it off. I never go online except to update hoster. Also, when i purchased my new laptop, it had a Napster player and software on it. It to, messed up hoster. So i unloaded all the junk programs that came with my lappy, and Hoster cruises along pretty well now. Just a thought.
