I think there might have been some confusion as to the terms used. The "Host" computer is the computer that the LogMeIn softare is installed on; this is the computer you are logging into. The "Client" is the computer that you are using to log in with.
When I said to try rebooting the host, I meant the computer that you are loggin in to.
I hope this clears things up, but if you still need help, we are always happy to provide assistance online.
