All of a sudden, I am unable to log into WI Security app on both my I phone and iMac despite entering the correct username and password. I just bought the app last week and performance was sketchy at best...it kept shutting off and either would not allow me to connect to the internet or timed out. Im very disappointed with my purchase and I paid top dollar $60 for access on 5 devices. No one in my family wants to use use it because of these issues. I,ve spent way too much time fiddled around with Webroots applications.
