I have rebooted and same problem. I see an FTR services service and a FTR IM bot service, those are the only 2 services I have running. Should there be more if you are not using Argus?
then i have no clue.
try restarting the service from within windows/services. try to connect as soon as service has restarted.
maybe try disabling all firewalls and try to connect. in case firewall has not been setup correctly.
